TPS7A16 www.ti.com SBVS171F–DECEMBER2011–REVISEDOCTOBER2015 7.3 Feature Description 7.3.1 Enable(EN) The enable terminal is a high-voltage-tolerant terminal. A high input on EN actives the device and turns on the regulator.Forself-biasapplications,connectthisinputtotheV terminal. IN 7.3.2 RegulatedOutput(V ) OUT TheV terminalistheregulatedoutputbasedontherequiredvoltage.Theoutputhascurrentlimitation.During OUT initial power up, the regulator has a soft start incorporated to control the initial current through the pass element. In the event that the regulator drops out of regulation, the output tracks the input minus a drop based on the load current.WhentheinputvoltagedropsbelowtheUVLOthreshold,theregulatorshutsdownuntiltheinputvoltage recoversabovetheminimumstart-uplevel. 7.3.3 Power-Good The power-good (PG) pin is an open-drain output and can be connected to any 5-V or lower rail through an external pull-up resistor. When no C is used, the PG output is high-impedance when V is greater than DELAY OUT thePGtripthreshold(V ).IfV dropsbelowV ,theopen-drainoutputturnsonandpullsthePGoutputlow.If IT OUT IT outputvoltagemonitoringisnotneeded,thePGpincanbeleftfloatingorconnectedtoGND. Thepower-goodfeaturefunctionalityisonlyguaranteedwhenV ≥3V(V ) IN IN_(MIN) 7.3.4 PGDelayTimer(DELAY) The power-good delay time (t ) is defined as the time period from when V exceeds the PG trip threshold DELAY OUT voltage (V ) to when the PG output is high. This power-good delay time is set by an external capacitor (C ) IT DELAY connected from the DELAY pin to GND; this capacitor is charged from 0 V to approximately 1.8 V by the DELAY pincurrent(I )onceV exceedsthePGtripthreshold(V ). DELAY OUT IT WhenC isused,thePGoutputishigh-impedancewhenV exceedsV ,andV exceedsV . DELAY OUT IT DELAY REF The power-good delay time can be calculated using: t = (C × V ) / I . For example, when C DELAY DELAY REF DELAY DELAY =10nF,thePGdelaytimeisapproximately12ms;thatis,(10nF ×1.193V)/1 µA=11.93ms. 7.3.5 InternalCurrentLimit The fixed internal current limit of the TPS7A16 family helps protect the regulator during fault conditions. The maximum amount of current the device can source is the current limit (225 mA, typical), and is largely independent of output voltage. For reliable operation, do not operate the device in current limit for extended periodsoftime. 7.3.6 ThermalProtection Thermal protection disables the output when the junction temperature rises to approximately 170°C, allowing the device to cool. When the junction temperature cools to approximately 150°C, the output circuitry is enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle ON and OFF. This cycling limits the dissipation of the regulator, protecting it from damage as a result of overheating.

In this mode of operation, the output voltage is the same as the input voltage minus the dropout voltage. The transient performance of the device is significantly degraded because the pass device (such as a bipolar junction transistor, or BJT) is in saturation and no longer controls the current through the LDO. Line or load transients in dropout can result in largeoutputvoltagedeviations. 7.4.3 Disabled Thedeviceisdisabledunderthefollowingconditions: • The enable voltage is less than the enable falling threshold voltage or has not yet exceeded the enable rising threshold. • Thedevicejunctiontemperatureisgreaterthanthethermalshutdowntemperature.

Events such as load-dump overvoltage (where the battery is disconnected while the alternator is providing current to a load) may cause voltage spikes from 25 V to 60 V. To prevent any damage to sensitive circuitry, localtransientvoltagesuppressorscanbeusedtocapvoltagespikestolower,moremanageablevoltages. The TPS7A16 family can be used to simplify and lower costs in such cases.

TPS7A16 www.ti.com SBVS171F–DECEMBER2011–REVISEDOCTOBER2015 8.2.3 MulticellBatteryPacks Currently, battery packs can employ up to a dozen cells in series that, when fully charged, may have voltages of up to 55 V. Internal circuitry in these battery packs is used to prevent overcurrent and overvoltage conditions that may degrade battery life or even pose a safety risk; this internal circuitry is often managed by a low-power microcontroller,suchasTI’sMSP430. The microcontroller continuously monitors the battery itself, whether the battery is in use or not. Although this microcontroller could be powered by an intermediate voltage taken from the multicell array, this approach unbalances the battery pack itself, degrading its life or adding cost to implement more complex cell balancing topologies. Thebestapproachtopowerthismicrocontrolleristoregulatedownthevoltagefromtheentirearraytodischarge everycellequallyandpreventanybalancingissues.Thisapproachreducessystemcomplexityandcost.

TPS7A16 SBVS171F–DECEMBER2011–REVISEDOCTOBER2015 www.ti.com 8.2.4 Battery-OperatedPowerTools High voltage multicell battery packs support high-power applications, such as power tools, with high current drain wheninuse,highlyintermittentusecycles,andphysicalseparationbetweenbatteryandmotor. In these applications, a microcontroller or microprocessor controls the motor. This microcontroller must be powered with a low-voltage rail coming from the high-voltage, multicell battery pack; as mentioned previously, powering this microcontroller or microprocessor from an intermediate voltage from the multicell array causes battery-pack life degradation or added system complexity because of cell balancing issues. In addition, this microcontroller or microprocessor must be protected from the high-voltage transients due to the motor inductance. The TPS7A16 can be used to power the motor-controlled microcontroller or microprocessor; its low quiescent current maximizes battery shelf life and its very high-voltage capabilities simplify system complexity by replacing voltagesuppressionfilters,thusloweringsystemcost. 100W Transient LDO First Optional 0.47mF M Cell Filter Second Cell MSP430 Microcontroller Last PWM Cell Figure20.

TPS7A16 www.ti.com SBVS171F–DECEMBER2011–REVISEDOCTOBER2015 9 Power Supply Recommendations The device is designed to operate from an input voltage supply with a range between 3 V and 60 V. This input supply must be well regulated. The TPS7A16 family of ultralow-power, high-voltage linear regulators achieve stability with a minimum input capacitance of 0.1 μF and output capacitance of 2.2 μF; however, TI recommends using10-μFceramiccapacitorstomaximizeacperformance. 10 Layout 10.1 Layout Guidelines To improve AC performance such as PSRR, output noise, and transient response, it is recommended that the board be designed with separate ground planes for IN and OUT, with each ground plane connected only at the GND pin of the device. In addition, the ground connection for the output capacitor should connect directly to the GNDpinofthedevice. Equivalent series inductance (ESL) and ESR must be minimized in order to maximize performance and ensure stability. Every capacitor must be placed as close as possible to the device and on the same side of the PCB as theregulatoritself. DonotplaceanyofthecapacitorsontheoppositesideofthePCBfromwheretheregulatorisinstalled.Theuse of vias and long traces is strongly discouraged because they may impact system performance negatively and evencauseinstability. If possible, and to ensure the maximum performance denoted in this product data sheet, use the same layout patternusedforTPS7A16evaluationboard,availableatwww.ti.com. 10.1.1 AdditionalLayoutConsiderations The high impedance of the FB pin makes the regulator sensitive to parasitic capacitances that may couple undesirable signals from near-by components (specially from logic and digital ICs, such as microcontrollers and microprocessors);thesecapacitively-coupledsignalsmayproduceundesirableoutputvoltagetransients.Inthese cases,TIrecommendsusingafixed-voltageversionoftheTPS7A16,orisolatetheFBnodebyfloodingthelocal PCBareawithground-planecoppertominimizeanyundesirablesignalcoupling. 10.2 Layout Example Layout is a critical part of good power-supply design. There are several signal paths that conduct fast-changing currents or voltages that can interact with stray inductance or parasitic capacitance to generate noise or degrade the power-supply performance. To help eliminate these problems, the IN pin should be bypassed to ground with alowESRceramicbypasscapacitorwithaX5RorX7Rdielectric. It may be possible to obtain acceptable performance with alternative PCB layouts; however, the layout and the schematichavebeenshowntoproducegoodresultsandaremeantasaguideline.

SuggestedLayout:BottomLayer 10.3 Power Dissipation The ability to remove heat from the die is different for each package type, presenting different considerations in the PCB layout. The PCB area around the device that is free of other components moves the heat from the device to the ambient air. Using heavier copper increases the effectiveness in removing heat from the device.

For reliable operation, junction temperature should be limited to a maximum of +125°C at the worst case ambient temperature for a given application. To estimate the margin of safety in a complete design (including the copper heat-spreading area), increase the ambient temperature until the thermal protection is triggered; use worst-case loads and signal conditions. For good reliability, thermal protection should trigger at least +45°C above the maximum expected ambient condition of the particular application. This configuration produces a worst-case junction temperature of +125°C at the highest expected ambient temperature and worst- caseload. The internal protection circuitry of the TPS7A16 has been designed to protect against overload conditions. It was not intended to replace proper heatsinking. Continuously running the TPS7A16 into thermal shutdown degrades devicereliability. Copyright©2011–2015,TexasInstrumentsIncorporated SubmitDocumentationFeedback 21 ProductFolderLinks:TPS7A16
