Overview

The NCV2903DMR2G is a dual, automotive-qualified differential comparator designed for high-reliability signal monitoring across a wide supply range of 2V to 36V. This AEC-Q100 qualified device features an open-collector output and is engineered for low-power operation, typically consuming only 0.4mA at 5V.

Why Choose This Part

The NCV2903DMR2G offers AEC-Q100 qualification and PPAP capability for demanding automotive safety and reliability standards. Its low input bias current of 0.25uA and wide supply range up to 36V provide significant design flexibility for both low-voltage battery applications and high-voltage industrial rails.

Applications

Automotive Threshold Detection
Used in battery monitoring and window comparator circuits for automotive 12V and 24V electrical systems.
Industrial Control Systems
Provides reliable limit sensing and alarm triggering in harsh industrial environments up to 125 degrees Celsius.
Power Supply Monitoring
Ideal for overvoltage or undervoltage lockout circuits due to its wide operating voltage range and open-collector output.
Logic Level Translation
Facilitates interfacing between different logic families (TTL, CMOS, DTL) through its open-collector output structure.

Getting Started

When designing with this comparator, ensure a pull-up resistor is connected to the open-collector output to establish the desired logic level. For automotive prototyping, place the 8-MSOP package on a breakout board and provide adequate decoupling capacitors near the Vcc pin to minimize noise in switching environments.
