Datasheet Details

Part number:

A1145

Manufacturer:

Allegro MicroSystems

File Size:

307.04 KB

Description:

Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches

Features

* ▪ Chopper stabilization ▫ Low switchpoint drift over operating temperature range ▫ Low sensitivity to stress ▪ Factory programmed at end-of-line for optimized switchpoints ▪ On-chip protection ▫ Supply transient protection ▫ Reverse-battery protection ▫ On-board voltage regulator ▫ 3.5 to 24 V opera

Applications

* these switches are utilized in sensing seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position. Two-wire unipolar switches, such as the A1145 and A1146, are particularly advantageous in price-sensitive applications because they require one less wire for oper
