Overview

The TMAG5123D1CQDBZR is a high-precision, in-plane omnipolar Hall-effect switch designed for wide input voltage ranges from 2.5V to 38V. It features a 30kHz continuous conversion rate and robust protection features, including 40V load dump and -20V reverse battery protection. The open-drain output simplifies interfacing with various logic levels in demanding industrial and automotive environments.

Why Choose This Part

This sensor offers exceptional robustness with integrated output short-circuit protection and current limiting. Its 30kHz sampling rate ensures fast response times, while the in-plane sensing technology allows for versatile mechanical mounting options compared to traditional through-hole Hall sensors.

Applications

Industrial Limit Switches
Used for end-of-travel detection in factory automation where high reliability and wide voltage ranges are required.
Vehicle Security Systems
Ideal for door and trunk latch sensing due to its reverse battery and load dump protection.
Liquid Level Sensing
Employed in non-contact float-based systems to monitor fluid levels without compromising seal integrity.
Consumer Appliances
Provides lid closure detection for washing machines and refrigerators using its high magnetic sensitivity.
