Description: Two-Wire Hall-Effect Switches

Features

* ▪ Choice of factory-set temperature coefficient (TC) for use with ferrite or rare-earth magnets ▪ Field programmable for optimized switchpoints ▪ AEC-Q100 automotive qualified ▫ On-board voltage regulator: 3 to 24 V operation ▪ High-speed, 4-phase chopper stabilization ▫ Low switchpoint drift throug

Applications

* These include sensing seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position. Two-wire unipolar switches are particularly advantageous in cost-sensitive applications because they require one less wire for operation versus the more traditional open-collector
