SN65HVD233,SN65HVD234,SN65HVD235 SLLS557H–NOVEMBER2002–REVISEDNOVEMBER2018 www.ti.com 5 Description (continued) Modes: The R pin (pin 8) of the SN65HVD233, SN65HVD234, and SN65HVD235 provides three modes of S operation: high-speed, slope control, and low-power standby mode. The high-speed mode of operation is selected by connecting pin 8 directly to ground, allowing the driver output transistors to switch on and off as fast as possible with no limitation on the rise and fall slope. The rise and fall slope can be adjusted by connecting a resistor between the R pin and ground. The slope will be proportional to the pin's output current. With a resistor S valueof10kΩ thedevicedriverwillhaveaslewrateof~15V/μsandwithavalueof100kΩ thedevicewillhave ~2.0V/μsslewrate.Formoreinformationaboutslopecontrol,refertoFeatureDescription. The SN65HVD233, SN65HVD234, and SN65HVD235 enter a low-current standby (listen only) mode during which the driver is switched off and the receiver remains active if a high logic level is applied to the R pin. If the S local protocol controller needs to transmit a message to the bus it will have to return the device to either high- speedmodeorslopecontrolmodeviatheR pin. S Loopback (SN65HVD233): A logic high on the loopback (LBK) pin (pin 5) of the SN65HVD233 places the bus output and bus input in a high-impedance state. Internally, the D to R path of the device remains active and available for driver to receiver loopback that can be used for self-diagnostic node functions without disturbing the bus.Formoreinformationontheloopbackmode,refertoFeatureDescription. Ultra Low-Current Sleep (SN65HVD234): The SN65HVD234 enters an ultra low-current sleep mode in which both the driver and receiver circuits are deactivated if a low logic level is applied to EN pin (pin 5). The device remainsinthissleepmodeuntilthecircuitisreactivatedbyapplyingahighlogicleveltopin5. Autobaud Loopback (SN65HVD235): The AB pin (pin 5) of the SN65HVD235 implements a bus listen-only loopback feature which allows the local node controller to synchronize its baud rate with that of the CAN bus. In autobaud mode, the bus output of the driver is placed in a high-impedance state while the bus input of the receiver remains active. There is an internal D pin to R pin loopback to assist the controller in baud rate detection,ortheautobaudfunction.Formoreinformationontheautobaudmode,refertoFeatureDescription. 6 Device Comparison Table(1) SLOPE DIAGNOSTIC AUTOBAUD PARTNUMBER LOWPOWERMODE CONTROL LOOPBACK LOOPBACK SN65HVD233D 200-μAstandbymode Adjustable Yes No SN65HVD234D 200-μAstandbymodeor50-nAsleepmode Adjustable No No SN65HVD235D 200-μAstandbymode Adjustable No Yes (1) Forthemostcurrentpackageandorderinginformation,seeMechanical,Packaging,andOrderableInformation,orseetheTIwebsite atwww.ti.com. 4 SubmitDocumentationFeedback Copyright©2002–2018,TexasInstrumentsIncorporated ProductFolderLinks:SN65HVD233 SN65HVD234 SN65HVD235

They are designed to interface between the differential bus lines in CAN and the CAN protocolcontrolleratdataratesupto1Mpbs. 10.2 Functional Block Diagrams R S CANH D CANL LBK R LBK Figure29.

SN65HVD35FunctionalBlockDiagram 10.3 Feature Description 10.3.1 DiagnosticLoopback(SN65HVD233) The diagnostic loopback or internal loopback function of the SN65HVD233 is enabled with a high-level input on pin 5, LBK. This mode disables the driver output while keeping the bus pins biased to the recessive state. This mode also redirects the D data input (transmit data) through logic to the received data output pin), thus creating an internal loopback of the transmit to receive data path. This mimics the loopback that occurs normally with a CAN transceiver because the receiver loops back the driven output to the R (receive data) pin. This mode allows the host protocol controller to input and read back a bit sequence or CAN messages to perform diagnostic routineswithoutdisturbingtheCANbus.AtypicalCANbusapplicationisdisplayedinFigure36.

However, it is pulled low internally (defaults to a low- levelinput)andmaybeleftopenifnotinuse. 10.3.2 AutobaudLoopback(SN65HVD235) The autobaud loopback mode of the SN65HVD235 is enabled by placing a high level input on pin 5, AB. In autobaudmode,thedriveroutputisdisabled,thusblockingtheDpintobuspathandthebustransmitfunctionof the transceiver. The bus pins remain biased to recessive. The receiver to R pin path or the bus receive function of the device remains operational, allowing bus activity to be monitored. In addition, the autobaud mode adds an internallogicloopbackpathfromtheDpintoRpinsothelocalnodemaytransmittoitselfinsyncwithbustraffic while not disturbing messages on the bus. Thus if the local node’s CAN controller generates an error frame, it is not transmitted to the bus, but is detected only by the local CAN controller. This is especially helpful to determine if the local node is set to the same baud rate as the network, and if not adjust it to the network baud rate (autobauddetection). Autobaud detection is best suited to applications that have a known selection of baud rates. For example, a popular industrial application has optional settings of 125 kbps, 250 kbps, or 500 kbps. Once the SN65HVD235 is placed into autobaud loopback mode the application software could assume the first baud rate of 125 kbps. It then waits for a message to be transmitted by another node on the bus. If the wrong baud rate has been selected, an error message is generated by the local CAN controller because the sample times will not be at the correct time. However, because the bus-transmit function of the device has been disabled, no other nodes receivetheerrorframegeneratedbythisnode'slocalCANcontroller. The application would then make use of the status register indications of the local CAN controller for message received and error warning status to determine if the set baud rate is correct or not. The warning status indicates that the CAN controller error counters have been incremented. A message received status indicates that a good message has been received. If an error is generated, the application would then set the CAN controller with the next possibly valid baud rate, and wait to receive another message. This pattern is repeated until an error free message has been received, thus the correct baud rate has been selected. At this point the application would place the SN65HVD235 in a normal transmitting mode by setting pin 5 to a low-level, thus enabling bus-transmit andbus-receivefunctionstonormaloperatingstatesforthetransceiver. If the AB pin is not used it may be tied to ground (GND). However, it is pulled low internally (defaults to a low- levelinput)andmaybeleftopenifnotinuse. 10.3.3 SlopeControl The rise and fall slope of the SN65HVD233, SN65HVD234, and SN65HVD235 driver output can be adjusted by connectingaresistorfromtheRs(pin8)toground(GND),ortoalow-levelinputvoltageasshowninFigure32. The slope of the driver output signal is proportional to the pin's output current. This slope control is implemented withanexternalresistorvalueof10kΩtoachievea~15V/μsslewrate,andupto100kΩ toachievea~2.0V/μs slew rate .

The shutdown condition is cleared when the junction temperature drops below the thermal shutdown temperature of the device. The CAN bus pins are high impedance biased to recessive level during a thermal shutdown, and the receiver to R pin path remains operational. 10.4 Device Functional Modes 10.4.1 DriverandReceiver Table2.Driver(SN65HVD233orSN65HVD235) INPUTS OUTPUTS D LBK/AB R CANH CANL BUSSTATE s X X >0.75V Z Z Recessive CC L Loropen H L Dominant ≤0.33V CC Horopen X Z Z Recessive X H ≤0.33V Z Z Recessive CC Copyright©2002–2018,TexasInstrumentsIncorporated SubmitDocumentationFeedback 21 ProductFolderLinks:SN65HVD233 SN65HVD234 SN65HVD235

TypicalHVD233Application 11.2.1 DesignRequirements 11.2.1.1 BusLoading,LengthandNumberofNodes The ISO 11898 Standard specifies up to a data rate of 1 Mbps, maximum CAN bus cable length of 40 m, maximum drop line (stub) length of 0.3 m and a maximum of 30 nodes. However, with careful network design, the system may have longer cables, longer stub lengths, and many more nodes to a bus. Many CAN organizations and standards have scaled the use of CAN for applications outside the original ISO 11898 standard. They have made system level trade-offs for data rate, cable length, and parasitic loading of the bus. ExamplesofsomeofthesespecificationsareARINC825,CANopen,CANKingdom,DeviceNetandNMEA200. A high number of nodes requires a transceiver with high input impedance and wide common mode range such as the SN65HVD23x CAN family. ISO 11898-2 specifies the driver differential output with a 60-Ω load (two 120- Ω termination resistors in parallel) and the differential output must be greater than 1.5 V. The SN65HVD23x devicesarespecifiedtomeetthe1.5-Vrequirementwitha60-Ω load,andadditionallyspecifiedwithadifferential output voltage minimum of 1.2 V across a common mode range of –2 V to 7 V through a 330-Ω coupling network. This network represents the bus loading of 120 SN65HVD23x transceivers based on their minimum differential input resistance of 40 kΩ. Therefore, the SN65HVD23x supports up to 120 transceivers on a single bussegmentwithmargintothe1.2-Vminimumdifferentialinputvoltagerequirementateachnode. For CAN network design, margin must be given for signal loss across the system and cabling, parasitic loadings, network imbalances, ground offsets and signal integrity thus a practical maximum number of nodes may be lower. Bus length may also be extended beyond the original ISO 11898 standard of 40 m by careful system designanddataratetradeoffs.Forexample,CANopennetworkdesignguidelinesallowthenetworktobeupto1 kmwithchangesintheterminationresistance,cabling,lessthan64nodesandsignificantlylowereddatarate.

Resistors equal to the characteristic impedance of the line should be used to O terminate both ends of the cable to prevent signal reflections. Unterminated drop lines (stubs) connecting nodes to the bus should be kept as short as possible to minimize signal reflections. The termination may be on the cable or in a node, but if nodes may be removed from the bus the termination must be carefully placed so that it isnotremovedfromthebus. 24 SubmitDocumentationFeedback Copyright©2002–2018,TexasInstrumentsIncorporated ProductFolderLinks:SN65HVD233 SN65HVD234 SN65HVD235

TypicalCANBus Termination is typically a 120-Ω resistor at each end of the bus. If filtering and stabilization of the common mode voltage of the bus is desired, then split termination may be used (see Figure 38). Split termination uses two 60-Ω resistors with a capacitor in the middle of these resistors to ground. Split termination improves the electromagnetic emissions behavior of the network by eliminating fluctuations in the bus common mode voltages atthestartandendofmessagetransmissions. Care should be taken in the power ratings of the termination resistors used.

However, some are concerned about the interoperability with 5 V supplied transceivers on the same bus. This report analyzesthissituationtoaddressthoseconcerns. 11.3.1.2 DifferentialSignal CAN is a differential bus where complementary signals are sent over two wires and the voltage difference between the two wires defines the logical state of the bus. The differential CAN receiver monitors this voltage differenceandoutputsthebusstatewithasingleendedlogicleveloutputsignal. 26 SubmitDocumentationFeedback Copyright©2002–2018,TexasInstrumentsIncorporated ProductFolderLinks:SN65HVD233 SN65HVD234 SN65HVD235

TypicalSN65HVD230DifferentialOutputVoltageWaveform The CAN driver creates the differential voltage between CANH and CANL in the dominant state. The dominant differential output of the SN65HVD23x is greater than 1.5 V and less than 3 V across a 60 ohm load as defined by the ISO 11898 standard. These are the same limiting values for 5 V supplied CAN transceivers. The bus terminationresistorsdrivetherecessivebusstateandnottheCANdriver. ACANreceiverisrequiredtooutputarecessivestatewhenlessthan500mVofdifferentialvoltageexistsonthe bus, and a dominant state when more than 900 mV of differential voltage exists on the bus. The CAN receiver must do this with common-mode input voltages from –2 V to 7 V. The SN65HVD23x family receivers meet these sameinputspecificationsas5Vsuppliedreceivers. 11.3.1.3 Common-ModeSignal A common-mode signal is an average voltage of the two signal wires that the differential receiver rejects. The common-mode signal comes from the CAN driver, ground noise, and coupled bus noise. Since the bias voltage of the recessive state of the device is dependent on V , any noise present or variation of V will have an effect CC CC on this bias voltage seen by the bus. The SN65HVD23x family has the recessive bias voltage set higher than 0.5*V to comply with the ISO 11898-2 CAN standard. The caveat to this is that the common mode voltage will CC drop by a couple hundred millivolts when driving a dominant bit on the bus. This means that there is a common mode shift between the dominant bit and recessive bit states of the device. While this is not ideal, this small variation in the driver common-mode output is rejected by differential receivers and does not effect data, signal noisemarginsorerrorrates. 11.3.1.4 Interoperabilityof3.3-VCANin5-VCANSystems The 3.3-V supplied SN65HVD23x family of CAN transceivers are fully compatible with 5-V CAN transceivers. The differential output voltage is the same, the recessive common mode output bias is the same, and the receivers have the same input specifications. The only slight difference is in the dominant common mode output voltagewhichisacouplehundredmillivoltslowerfor3.3-VCANtransceiverthan5-Vsuppliedtransceiver. To help ensure the widest interoperability possible, the SN65HVD23x family has successfully passed the internationally recognized GIFT/ICT conformance and interoperability testing for CAN transceivers. Electrical interoperability does not always assure interchangeability however. Most implementers of CAN buses recognize that ISO 11898 does not sufficiently specify the electrical layer and that strict standard compliance alone does notensurefullinterchangeability.Thiscomesonlywiththoroughequipmenttesting.

The TPS76333 is a linear voltage CC regulatorsuitableforthe3.3Vsupply. 13 Layout 13.1 Layout Guidelines In order for the PCB design to be successful, start with design of the protection and filtering circuitry. Because ESD and EFT transients have a wide frequency bandwidth from approximately 3 MHz to 3 GHz, high frequency layout techniques must be applied during PCB design. On chip IEC ESD protection is good for laboratory and portable equipment but is usually not sufficient for EFT and surge transients occurring in industrial environments. Thereforerobustandreliablebusnodedesignrequirestheuseofexternaltransientprotectiondevicesatthebus connectors. Placement at the connector also prevents these harsh transient events from propagating further into thePCBandsystem. UseV andgroundplanestoprovidelowinductance. CC NOTE High frequency current follows the path of least inductance and not the path of least resistance. Design the bus protection components in the direction of the signal path. Do not force the transient current to divertfromthesignalpathtoreachtheprotectiondevice. An example placement of the Transient Voltage Suppression (TVS) device indicated as D1 (either bi-directional diodeorvaristorsolution)andbusfiltercapacitorsC8andC9areshowninFigure41. The bus transient protection and filtering components should be placed as close to the bus connector, J1, as possible. This prevents transients, ESD and noise from penetrating onto the board and disturbing otherdevices. Bus termination: Figure 41 shows split termination. This is where the termination is split into two resistors, R5 and R6, with the center or split tap of the termination connected to ground via capacitor C7. Split termination provides common mode filtering for the bus. When termination is placed on the board instead of directly on the bus, care must be taken to ensure the terminating node is not removed from the bus as this will cause signal integrity issues of the bus is not properly terminated on both ends. See the application section for information on powerratingsneededfortheterminationresistor(s). Bypass and bulk capacitors should be placed as close as possible to the supply pins of transceiver, examples C2,C3(V ). CC Use at least two vias for V and ground connections of bypass capacitors and protection devices to minimize CC traceandviainductance. Tolimitcurrentofdigitallines,serialresistorsmaybeused.ExamplesareR1,R2,R3andR4. To filter noise on the digital IO lines, a capacitor may be used close to the input side of the IO as shown by C1 andC4. Since the internal pullup and pulldown biasing of the device is weak for floating pins, an external 1-kΩ to 10-kΩ pullup or pulldown resistor should be used to bias the state of the pin more strongly against noise during transientevents. Pin 1: If an open drain host processor is used to drive the D pin of the device an external pull-up resistor between1kΩand10kΩ andV shouldbeusedtodrivetherecessiveinputstateofthedevice. CC Pin 8: is shown assuming the mode pin, RS, will be used. If the device will only be used in normal mode or slope controlmode,R3isnotneededandthepadsofC4couldbeusedforthepulldownresistortoGND. 28 SubmitDocumentationFeedback Copyright©2002–2018,TexasInstrumentsIncorporated ProductFolderLinks:SN65HVD233 SN65HVD234 SN65HVD235
