Sensitive Two-Wire Field-Programmable Chopper-Stabilized Unipolar Hall-Effect Switches

The A1180, A1181, A1182, and A1183 devices are sensitive, two-wire, unipolar, Hall effect switches. The operate point, BOP, CAN be field-programmed, after final packaging of the device and placement into the application. This advanced feature allows the optimization of the device 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 in sensing: 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 By Allegro MicroSystems, Inc.
