A1147 (A1147 / A1148) Low Current Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches

A1147 Description

A1147 and A1148 Low Current Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches .
The A1147 and A1148 devices are two-wire, unipolar, Hall effect switches that are factory-programmed at end-of-line to optimize ultrasensitive magneti.

A1147 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

A1147 Applications

* these switches are utilized to sense seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position. Two-wire unipolar switches, such as the A1147 and A1148, are particularly advantageous in price-sensitive applications because they require one less wire for operat
