Description
A119x and A119x-F Programmable, Chopper-Stabilized, Two-Wire Hall-Effect Switches .
The A119x and A119x-F comprise a family of two-wire, unipolar, Hall-effect switches, which can be trimmed by the user at end-of-line to optimize magne.
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
