A1156-F, A1152-F, Chopper-Stabilized Two-Wire Hall-Effect Switches

A1152-F, A1153-F, A1155-F, and A1156-F Chopper-Stabilized Two-Wire Hall-Effect Switches

Features

* ▪ AEC-Q100 automotive qualified ▪ Factory-set temperature coefficient (TC) for use with ferrite magnets ▪ High-speed, 4-phase chopper stabilization ▪ Low switchpoint drift throughout temperature range ▪ Low sensitivity to thermal and mechanical stresses ▪ On-chip protection ▫ Supply transient protec

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
