Overview

The LM2903AVQPWRG4Q1 is an automotive-qualified, dual-channel comparator designed for high-reliability applications. It features an open-collector output and a wide supply voltage range from 2V to 36V, making it compatible with standard 12V and 24V automotive systems. As a functional safety-capable device, it is specifically engineered for automotive and industrial environments requiring extended temperature performance from -40C to 125C.

Why Choose This Part

This comparator offers significant design flexibility with a wide common-mode input range that includes ground, even when operating from a single supply. Its AEC-Q100 qualification and functional safety-capable designation ensure high reliability in mission-critical automotive systems. The 8-TSSOP package provides a compact footprint while maintaining a robust operating temperature range up to 125C.

Applications

Body Control Modules
Used for monitoring door locks, lighting, and window controls where reliable threshold detection is required.
HEV/EV Power Trains
Ideal for battery management systems and inverter monitoring due to its high voltage tolerance and automotive qualification.
Industrial Sensor Interface
Functions as a signal conditioner or threshold detector for sensors in harsh industrial automation environments.
Voltage Monitoring
Utilized in over-voltage or under-voltage detection circuits with the ability to interface with different logic levels via the open-collector output.
