Overview

The LM2901QPWRQ1 is an automotive-qualified, quad-channel differential comparator designed for high-reliability applications. It features four independent voltage comparators with open-collector outputs, allowing for easy level shifting and wired-AND logic configurations across a wide supply voltage range from 2V to 30V.

Why Choose This Part

This AEC-Q100 qualified device offers excellent thermal stability across a -40C to 125C operating range, making it suitable for under-the-hood applications. Its open-collector output design simplifies multi-voltage system integration, and the low input bias current of 0.25uA minimizes loading on high-impedance sensor circuits.

Applications

Battery Management Systems (BMS)
Monitoring cell voltages and providing over-voltage or under-voltage fault detection in electric vehicle battery packs.
Body Control Modules
Interfacing with analog sensors to trigger digital logic for lighting, wiper control, and door locks.
Power Train Systems
Used in HEV/EV power electronics for threshold detection and signal conditioning in harsh thermal environments.
Infotainment and Cluster
Providing precise signal monitoring and diagnostic feedback for automotive dashboard displays and head units.

Getting Started

When designing with this comparator, ensure a pull-up resistor is connected to the open-collector output to establish the high-level logic voltage. Place a 0.1uF ceramic bypass capacitor close to the VCC pin to filter power supply noise, particularly in high-speed switching environments common in automotive power electronics.
