3 Description

The LM2901B-Q1 device is the next generation version of the industry-standard LM2901x-Q1 comparator family. This next generation family provides outstanding value for cost-sensitive applications, with features including lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2kV ESD performance with drop- in replacement convenience. All devices consist of four independent voltage comparators that are designed to operate over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is within 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. The outputs can be connected to other open-collector outputs. The "V" versions operate up to 32V, and the "B" version operates up to 36V. All are qualified for the AEC-Q100 Grade 1 temperature range of -40°C to +125°C.

The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state. Either or both inputs can go to maximum VCC level without damage. (2) This parameter is ensured by design and/or characterization and is not tested in production.

7 Detailed Description

7.1 Overview

The LM2901-Q1 family is a quad comparator with the ability to operate up to 36 V on the supply pin. 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 . 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. Please see Application Note SNOAA35 for more information

7.2 Functional Block Diagram

7.3 Feature Description

LM2901-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 LM2901-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 6-19 , Figure 6-20 and Figure 6-21 for V OL 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 LM2901-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. www.ti.com LM2901-Q1, LM2901V-Q1, LM2901AV-Q1, LM2901B-Q1 SLCS142G – DECEMBER 2003 – REVISED MARCH 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 17 Product Folder Links: LM2901-Q1 LM2901V-Q1 LM2901AV-Q1 LM2901B-Q1

8 Application and Implementation

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, as well as validating and testing their design implementation to confirm system functionality.

8.1 Application Information

LM2901-Q1 family 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 LM2901-Q1 optimal for level shifting to a higher or lower voltage.

8.2 Typical Application

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 choosing the input voltage range, the input common mode voltage range (V ICR) must be taken in to account. 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. 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 LM2901-Q1, LM2901V-Q1, LM2901AV-Q1, LM2901B-Q1 SLCS142G – DECEMBER 2003 – REVISED MARCH 2023 www.ti.com

Product Folder Links: LM2901-Q1 LM2901V-Q1 LM2901AV-Q1 LM2901B-Q1

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. The "B" version output will go high.

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 (V IO). To make an accurate comparison the overdrive voltage (V OD) must be higher than the input offset voltage (V IO). 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/pull-up resistance and logic/pull-up voltage. The output current will produce an output low voltage (V OL) which is proportional to the output current. Use Figure 6-19, Figure 6-20, and Figure 6-21 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.

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 R CE, use the slope of Figure 6-35 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. Output Voltage (V) Time (us) 5mV OD 20mV OD 100mV OD C001 Figure 8-2.

9 Power Supply Recommendations

For fast response and comparison applications with noisy or AC inputs, TI recommends using a bypass capacitor on the supply pin to reject any variation on the supply voltage. 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 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).
