Datasheet Details

Part number:

A1158, A1150

Manufacturer:

Allegro MicroSystems

File Size:

1.09 MB

Description:

Two Wire Hall-Effect Switches

Note:

This datasheet PDF includes multiple part numbers: A1158, A1150.
Please refer to the document for exact specifications by model.

Features

* AEC-Q100 automotive qualified
* High-speed, 4-phase chopper stabilization
* Low switchpoint drift throughout temperature range
* Low sensitivity to thermal and mechanical stresses
* On-chip protection
* Supply transient protection
* Reverse-b

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
