Description

The A1180, A1181, A1182, and A1183 devices are sensitive,

two-wire, unipolar, Hall effect switches. The operate point, B

can be field-programmed, after final packaging of the sensor

and placement into the application. This advanced feature

allows the optimization of the sensor switching performance,

by effectively accounting for variations caused by mounting

tolerances for the device and the target magnet.

This family of devices are produced on the Allegro

MicroSystems advanced BiCMOS wafer fabrication process,

which implements a patented, high-frequency, chopper-

stabilization technique that achieves magnetic stability and

eliminates the offsets that are inherent in single-element devices

exposed to harsh application environments. Commonly found

in a number of automotive applications, the A1180-83 family of

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 open-collector output

Packages: 3 pin SOT23W (suffix LH), and

3 pin SIP (suffix UA)
