This standard device has proven ubiquity and versatility across a wide range of applications. This is due to it's very wide supply voltages range (2 V to 36 V), low Iq and fast response. This device is AEC-Q100 qualified and can operate over a wide temperature range of –40°C to 125°C (LM2903Q1 and LM2903B-Q1) or –40°C to 150°C (LM2903E-Q1). The open-drain output allows the user to configure the output's logic low voltage (V OL) and can be utilized to enable the comparator to be used in AND functionality. The "B" versions add dedicated ESD protections on all the pins for improved ESD performance as well as improved negative input voltage handling.

Schematic (Each Comparator) 4.3 Feature Description LM2903-Q1 family 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 LM2903-Q1 to accurately function from ground to V CC–1.5V differential input. This is enables much head room for modern day supplies of 3.3 V and 5.0 V. The output consists of an open drain NPN (pull-down or low side) transistor. The output NPN will sink current when the negative input voltage is higher than the positive input voltage and the offset voltage. The VOL is resistive and will scale with the output current. Please see Figure 3-3 in the Section 3.14 section for V OL values with respect to the output current. 4.4 Device Functional Modes 4.4.1 Voltage Comparison The LM2903-Q1 family 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 pull-up) based on the input differential polarity.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 5.1 Application Information LM2903-Q1 will typically be 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 LM2903Q1 optimal for level shifting to a higher or lower voltage. 5.2 Typical Application VLOGIC VLOGIC VSUP Vin VSUP Rpullup + Vin+ ½ LM2903 Rpullup + ½ LM2903 Vin- Vref CL CL Figure 5-1. Single-ended and Differential Comparator Configurations 5.2.1 Design Requirements For this design example, use the parameters listed in Table 5-1 as the input parameters. Table 5-1.

If temperature operation is above or below 25°C the V ICR can range from 0 V to V CC– 2.0 V. This limits the input voltage range to as high as V CC– 2.0 V and as low as 0 V. Operation outside of this range can yield incorrect comparisons. 16 Submit Document Feedback Copyright © 2020 Texas Instruments Incorporated Product Folder Links: LM2903-Q1 LM2903B-Q1 LM2903-Q1, LM2903B-Q1 www.ti.com SLCS141J – MAY 2003 – REVISED NOVEMBER 2020 Below is a list of input voltage situation and their outcomes: 1. When both IN- and IN+ are both within the common mode range: a. If IN- is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking current b. If IN- is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is not conducting 2. When IN- is higher than common mode and IN+ is within common mode, the output is low and the output transistor is sinking current 3. When IN+ is higher than common mode and IN- is within common mode, the output is high impedance and the output transistor is not conducting 4. When IN- and IN+ are both higher than common mode, the output is low and the output transistor is sinking current 5.2.2.2 Minimum Overdrive Voltage Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the comparator over the offset voltage (V IO). In order to make an accurate comparison the Overdrive Voltage (V OD) should be higher than the input offset voltage (V IO). Overdrive voltage can also determine the response time of the comparator, with the response time decreasing with increasing overdrive. Figure 5-2 and Figure 5-3 show positive and negative response times with respect to overdrive voltage. 5.2.2.3 Output and Drive Current Output current is determined by the load/pull-up resistance and logic/pull-up voltage. The output current will produce a output low voltage (V OL) from the comparator. In which V OL is proportional to the output current. Use Figure 3-5 to determine VOL based on the output current. The output current can also effect the transient response. More will be explained in the next section. 5.2.2.4 Response Time The transient response can be determined by the load capacitance (C L), load/pull-up resistance (R PULLUP) and equivalent collector-emitter resistance (RCE). • • The positive response time (τp) is approximately τP ~ RPULLUP × CL The negative response time (τN) is approximately τN ~ RCE × CL – RCE can be determine by taking the slope of Figure 3-5 in it's linear region at the desired temperature, or by dividing the VOL by Iout 5.2.3 Application Curves 6 6 5 5 Output Voltage (Vo) Output Voltage, Vo(V) The following curves were generated with 5 V on VCC and VLogic, RPULLUP = 5.1 kΩ, and 50 pF scope probe. 4 3 5mV OD 2 1 20mV OD 0 4 3 2 5mV OD 1 20mV OD 0 100mV OD ±1 -0.25 0.25 0.75 1.25 Time (usec) 1.75 100mV OD ±1 ±0.25 0.00 2.25 Figure 5-2.

This variation can eat into the comparator's input common mode range and create an inaccurate comparison. 7 Layout 7.1 Layout Guidelines For accurate comparator applications without hysteresis it is important maintain a stable power supply with minimized noise and glitches, which can affect the high level input common mode voltage range. In order 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 negative supply is not being used, do not put a capacitor between the IC's GND pin and system ground. 7.2 Layout Example Ground Bypass Capacitor Negative Supply or Ground Only needed for dual power supplies 1OUT 1INí 1IN+ GND 1 2 3 4 0.1PF VCC 7 2OUT 6 2INí 5 2IN+ 8 Positive Supply 0.1PF Ground Figure 7-1.
