This device has proven ubiquity and versatility across a wide range of applications. This is due to verywidesupplyvoltagesrange,lowIqandfastresponseofthedevices. The open-drain output allows the user to configure the output's logic high voltage (V ) and can be used to OH enablethecomparatortobeusedinANDfunctionality. 7.2 Functional Block Diagram VCC 80-µA CurrentRegulator 10µA 60µA 10µA 80µA COMPONENT COUNT Epi-FET 1 Diodes 2 IN+ Resistors 2 OUT Transistors 30 IN− GND Figure38. Schematic(EachComparator) 7.3 Feature Description The comparator consists of a PNP darlington pair input, allowing the device to operate with very high gain and fast response with minimal input bias current. The input Darlington pair creates a limit on the input common mode voltage capability, allowing the comparator to accurately function from ground to V – 1.5 V input. Allow CC forV –2Vatcoldtemperature. CC The output consists of an open drain NPN (pull-down or low side) transistor. The output NPN sinks current when thenegativeinputvoltageishigherthan the positive input voltage and the offset voltage. The V is resistive and OL scaleswiththeoutputcurrent.SeeFigure3 forV valueswithrespecttotheoutputcurrent. OL 7.4 Device Functional Modes 7.4.1 VoltageComparison The device operates solely as a voltage comparator, comparing the differential voltage between the positive and negative pins and outputting a logic low or high impedance (logic high with pullup) based on the input differential polarity. 18 SubmitDocumentationFeedback Copyright©1979–2020,TexasInstrumentsIncorporated ProductFolderLinks:LM393B LM2903B LM193 LM293 LM293A LM393 LM393A LM2903 LM2903V

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The device is typically used to compare a single signal to a reference or two signals against each other. Many users take advantage of the open drain output to drive the comparison logic output to a logic voltage level to an MCU or logic device. The wide supply range and high voltage capability makes this comaprator optimal for level shiftingtoahigherorlowervoltage. 8.2 Typical Application V V LOGIC LOGIC V V SUP Rpullup SUP Rpullup Vin + Vin+ + ½ LM2903 ½ LM2903 Vref Vin- C C L L Figure39.

If temperature operation is below 25°C the V can range from 0 V to V – 2.0 V. This limits the input ICR CC voltage range to as high as V – 2.0 V and as low as 0 V. Operation outside of this range can yield incorrect CC comparisons.

To make an accurate comparison the Overdrive Voltage (V ) should be higher IO OD than the input offset voltage (V ). Overdrive voltage can also determine the response time of the comparator, IO withtheresponsetimedecreasingwithincreasingoverdrive.Figure 40 and Figure 41 show positive and negative responsetimeswithrespecttooverdrivevoltage. 8.2.2.3 OutputandDriveCurrent Output current is determined by the load/pull-up resistance and logic/pullup voltage. The output current produces a output low voltage (V ) from the comparator. In which V is proportional to the output current.

This variation can eat into the input common-moderangeofthecomparatorandcreateaninaccuratecomparison. 10 Layout 10.1 Layout Guidelines For accurate comparator applications without hysteresis it is important maintain a stable power supply with minimized noise and glitches. To achieve this, it is best to add a bypass capacitor between the supply voltage and ground. This should be implemented on the positive power supply and negative supply (if available). If a negativesupplyisnotbeingused,donotputacapacitorbetweentheIC'sGNDpinandsystemground. Minimize coupling between outputs and inverting inputs to prevent output oscillations. Do not run output and inverting input traces in parallel unless there is a V or GND trace between output and inverting input traces to CC reducecoupling.Whenseriesresistanceisaddedtoinputs,placeresistorclosetothedevice. 10.2 Layout Example Better Ground (cid:19)(cid:17)(cid:20)PF 1 1OUT VCC 8 VCC Input Resistors Close to device 2 1IN- 2OUT 7 OK VCC or GND 3 1IN+ 2IN- 6 Ground 4 GND 2IN+ 5 Figure42.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. Addendum-Page 5
