Description
A1150, A1152, A1153, A1155, A1156, A1157, and A1158 Chopper-Stabilized, Two-Wire Hall-Effect Switches .
The A1150, A1152, A1153, A1155, A1156, A1157, and A1158 comprise a family of two-wire, unipolar, Hall-effect switches, which are factory-trimmed to op.
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
