Overview
The LM2901VQPWRCT is a quad automotive comparator from the LM2901x-Q1 family, manufactured by Texas Instruments. It operates on single or dual supplies ranging from 2 V to 32 V. The device features four independent voltage comparators with open-drain outputs compatible with TTL, MOS, and CMOS logic. It supports an ambient operating temperature range of -40°C to +125°C and includes AEC-Q100 Grade 1 qualification.
Feature Summary
- AEC-Q100 qualified for automotive applications with specified HBM and CDM ESD classification levels
- Low supply current consumption that remains independent of the supply voltage
- Differential input voltage range equal to the maximum-rated supply voltage
- Common-mode input voltage range includes ground potential
Applications
- HEV/EV and power train systems
- Infotainment and cluster modules
- Body control modules
- Industrial equipment
- Appliances
Procurement Notes
Verify the specific suffix CT indicates cut tape packaging configuration against the manufacturer's orderable addendum. Confirm the V suffix denotes the 32 V maximum supply rating variant within the LM2901x-Q1 family. Ensure the PW package designation matches the required TSSOP-14 footprint for the target PCB layout.
Selection Notes
Select this component when automotive reliability and wide supply voltage operation are required. The V suffix provides a 32 V limit compared to the 30 V non-V versions. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate thermal resistance metrics if high ambient temperatures or dense board layouts are present in the design.
Part Context
This part belongs to the LM2901-Q1 quadruple automotive comparator family. It serves as a standard industry replacement for general-purpose voltage comparison tasks in harsh environments. The family includes variants like LM2901B-Q1 and LM2901AV-Q1 with differing offset voltages and supply limits.

FAQ
What is the maximum supply voltage for the V suffix version?
The V suffix versions, including LM2901V-Q1, support a maximum supply voltage of 32 V.
Does the device support dual supply operation?
Yes, the device can operate from dual supplies provided the difference between them is within 2 V to 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage.
