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 and higher supply voltage capability. Additionally, 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 2V to 36V, and VCC is at least 1.5V 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.

6 Detailed Description

6.1 Overview

The LM2901-Q1 family is a quad comparator with the ability to operate up to 36V 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 (2V to 36V), 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

• Input Q9 Q10 Q11 Q5 Q6 D2 D3 Q12 + Input Output VCC Internal Bias Itail I1 I2 Q13 Q14 ESD ESD VCM Clamp Q15

6.3 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 CC– 2V over temperature. On the non-B devices, a clamp was added around Q3 to mimic the both inputs above input voltage range behavior of the original classic silicon. The output consists of an open drain NPN (pull-down or low side) transistor. The output NPN sinks current when the negative input voltage is higher than the positive input voltage and the offset voltage. The V OL is resistive and scales with the output current. Please see the "Output Low Voltage vs. Output Sinking Current" graphs for VOL values with respect to the output current.

6.4 Device Functional Modes

6.4.1 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 SLCS142H – DECEMBER 2003 – REVISED MAY 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 15 Product Folder Links: LM2901-Q1 LM2901V-Q1 LM2901AV-Q1 LM2901B-Q1

7 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.

7.1 Application Information

LM2901-Q1 family 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 LM2901-Q1 an excellent choice for level shifting to a higher or lower voltage.

7.2.1 Design Requirements

For this design example, use the parameters listed in Table 7-1 as the input parameters. Table 7-1. Design Parameters PARAMETER EXAMPLE VALUE Input voltage range 0V to VSUP – 1.5V Supply voltage 2V to 36V Logic supply voltage 2V to 36V Output current (RPULLUP) 1µA to 20mA Input overdrive voltage 100mV Reference voltage 2.5V Load capacitance (CL) 15pF

7.2.2 Detailed Design Procedure

7.2.2.1 Input Voltage Range

When choosing the input voltage range, the input common mode voltage range (V ICR) must be taken into account. If temperature operation is above or below 25°C the V ICR can range from 0V to V CC– 2.0V. This limits the input voltage range to as high as V CC– 2.0V and as low as 0V. Operation outside of this range can yield incorrect comparisons. Below is a list of input voltage situation and the outcomes: 1. When both IN- and IN+ are both within the common mode range: LM2901-Q1, LM2901V-Q1, LM2901AV-Q1, LM2901B-Q1 SLCS142H – DECEMBER 2003 – REVISED MAY 2025 www.ti.com

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, see Section 2 of Application Design Guidelines for LM339, LM393, TL331 Family Comparators Including the New B-versions.

7.2.2.2 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 7-2 and Figure 7-3 show positive and negative response times with respect to overdrive voltage.

7.2.2.3 Output and Drive Current

Output current is determined by the load/pull-up resistance and logic/pull-up voltage. The output current produces a output low voltage (V OL) which is proportional to the output current. Use Figure 5-19, Figure 5-20, and Figure 5-21 to determine VOL based on the output current. The output current can also effect the transient response. More is explained in the next section.

7.2.2.4 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 5-31 in the linear region at the desired temperature, or divide VOL by IO.

7.2.3 Application Curves

The following curves were generated with 5V on VCC and VLOGIC, RPULLUP = 5.1kΩ, and 50pF scope probe. www.ti.com LM2901-Q1, LM2901V-Q1, LM2901AV-Q1, LM2901B-Q1 SLCS142H – DECEMBER 2003 – REVISED MAY 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 17 Product Folder Links: LM2901-Q1 LM2901V-Q1 LM2901AV-Q1 LM2901B-Q1

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.

7.3 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.

7.4 Layout

7.4.1 Layout Guidelines

For accurate comparator applications without hysteresis maintaining a stable power supply with minimized noise and glitches is critical. Best practice is to add a bypass capacitor between the supply voltage and ground. This can 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 GND pin and system ground. 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 CC or GND trace between output and inverting input traces to reduce coupling. When series resistance is added to inputs, place resistor close to the device. LM2901-Q1, LM2901V-Q1, LM2901AV-Q1, LM2901B-Q1 SLCS142H – DECEMBER 2003 – REVISED MAY 2025 www.ti.com
