Description
Unipolar Hall-Effect Switches

Features

* Chopper stabilization Low switchpoint drift over operating temperature range Low stress sensitivity Field-programmable for optimized switchpoints On-chip protection Supply transient protection Reverse-battery protection On-board voltage regulator 3.5 V to 24 V operation A1185-DS, Rev. 1 Allegro

Applications

* the A1185 and A1186 devices are utilized to sense: seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position. Two-wire unipolar switches are particularly advantageous in price-sensitive applications, because they require one less wire than the more traditional
