This standard device has proven ubiquity and versatility across a wide range of applications because of the very wide supply voltage range (2 V to 30 V or 32 V), low IQ, and fast response of the device. This device is AEC-Q100 qualified and can operate over a wide temperature range (–40°C to 125°C). The open-collector output allows the user to configure the logic-high voltage of the output (VOH) independent of VCC and can be used with multiple comparators in wired AND functionality. 7.2 Functional Block Diagram VCC 80-µA Current Regulator 60 µA 10 µA 10 µA 80-µA IN+ OUT IN– GND Copyright © 2016, Texas Instruments Incorporated 7.3 Feature Description The LM2901x-Q1 family of devices 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 ability, allowing the LM2901x-Q1 family of devices to accurately function from ground to VCC – 2 V for the lower voltage input. The higher voltage input may go up to the maximum VCC. This ability enables a wide input range even when using modern-day supplies of 3.3 V and 5 V. The output consists of an open collector bipolar transistor. The transistor sinks current when the negative input voltage is higher than the positive input voltage and the offset voltage. The VOL is resistive and scales with the output current. See Figure 6-3 in Section 6.7 for the VOL values with respect to the output current. The special pinout of this device separates input pins from the output pins to reduce parasitic coupling between input and output. 7.4 Device Functional Modes 7.4.1 Voltage Comparison The LM2901x-Q1 family of devices operates solely as a voltage comparator, comparing the differential voltage between the positive and negative pins and outputs a logic low or high impedance (logic high with pullup) based on the input differential polarity. 8 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: LM2901-Q1 LM2901V-Q1 LM2901AV-Q1 LM2901-Q1, LM2901V-Q1, LM2901AV-Q1 www.ti.com SLCS142F – DECEMBER 2003 – REVISED MAY 2021 8 Application and Implementation Note Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. 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. 8.1 Application Information The LM2901x-Q1 family of devices 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 the LM2901x-Q1 family of devices optimal for level shifting to a higher or lower voltage. 8.2 Typical Application VLOGIC VSUP VxIN+ RPULLUP + RPULLUP VxIN+ ½ LM2901x-Q1 VREF VLOGIC VSUP ½ LM2901x-Q1 VxIN– – – CL CL Copyright © 2016, Texas Instruments Incorporated Figure 8-1. Single-Ended and Differential Comparator Configurations 8.2.1 Design Requirements For this design example, use the parameters listed in Table 8-1 as the input parameters. Table 8-1. Design Parameters PARAMETER EXAMPLE VALUE Input voltage range 0 V to VSUP – 1.5 V Supply voltage 2 V to 36 V Logic supply voltage 2 V to 36 V Output current (RPULLUP) 1 µA to 20 mA Input overdrive voltage 100 mV Reference voltage 2.5 V Load capacitance (CL) 15 pF 8.2.2 Detailed Design Procedure 8.2.2.1 Input Voltage Range When selecting the input voltage range, the input common-mode voltage range (VICR) must be considered. If temperature operation is above or below 25°C the VICR can range from 0 V to VCC – 2 V. The VICR range limits the input voltage range to as high as VCC – 2 V and as low as 0 V. Operation outside of this range can yield incorrect comparisons. The following lists some input voltage scenarios and the resulting outcomes: • When both IN– and IN+ are both within the common-mode range: – If IN– is higher than IN+ and the offset voltage, then the output is low and the output transistor is sinking current.

When IN– is higher than common-mode and IN+ is within common-mode, the output is low and the output transistor is sinking current. When IN+ is higher than common-mode and IN– is within common-mode, then the output is in high impedance and the output transistor is not conducting. When IN– and IN+ are both higher than common-mode, then the output is low and the output transistor is sinking current. • • • 8.2.2.2 Minimum Overdrive Voltage The overdrive voltage is the differential voltage produced between the positive and negative inputs of the comparator over the offset voltage (VIO). To make an accurate comparison the overdrive voltage (VOD) must be higher than the input offset voltage (VIO). The overdrive voltage can also determine the response time of the comparator, with the response time decreasing as the overdrive increases. Figure 8-2 and Figure 8-3 show positive and negative response times with respect to overdrive voltage. 8.2.2.3 Output and Drive Current Output current is determined by the load or pullup resistance and logic or pullup voltage. The output current produces an output low voltage (VOL) from the comparator. In which VOL is proportional to the output current. Use Figure 6-3 to determine VOL based on the output current. The output current can also effect the transient response. See Section 8.2.2.4 for more information. 8.2.2.4 Response Time The transient response can be determined by the load capacitance (CL), load or pullup resistance (RPULLUP), and equivalent collector-emitter resistance (RCE). Use Equation 1 and Equation 2 to calculate the approximate values of the rise time (tr) and fall time (tf). tP ≈ RPULLUP × CL (1) tN ≈ RCE × CL (2) To find the value of RCE, use the slope of Figure 6-3 in the linear region at the desired temperature, or divide VOL by IO. 8.2.3 Application Curves The following curves were generated with 5 V on VCC and VLOGIC, RPULLUP = 5.1 kΩ, and 50-pF scope probe. 6 6 5 20mV OD 5 4 100mV OD 4 Output Voltage (V) Output Voltage (V) 5mV OD 3 2 1 0 3 2 1 5mV OD 0 20mV OD 100mV OD ±1 ±1 0.0 0.5 1.0 1.5 Time (us) 2.0 2.5 Submit Document Feedback 0.5 1.0 1.5 Time (us) C001 Figure 8-2.

This variation can take away from some of the input common mode range of the comparator and create an inaccurate comparison. 10 Layout 10.1 Layout Guidelines For accurate comparator applications without hysteresis, maintaining a stable power supply with minimized noise and glitches, which can affect the high-level input common-mode voltage range, is important. To achieve a stable power supply, place a bypass capacitor between the positive and negative (if available) supply voltage and ground. If a negative supply is not being used, do not put a capacitor between the GND pin of the IC and system ground. 10.2 Layout Example Ground Bypass Capacitor 1OUT 2OUT VCC 2IN– 2IN+ 1IN– 1IN+ 0.1 μF Positive Supply 1 2 14 3OUT 13 4OUT 3 12 GND 4 5 6 7 11 4IN+ 10 4IN– 9 3IN+ 8 3IN– Negative Supply or Ground Only needed for dual power 0.1 μF supplies Ground Figure 10-1.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 11.5 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 12 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.
