|
The A1145 and A1146 devices are two-wire, unipolar, Hall effect switches that are factory-programmed at end-of-line to optimize ultrasensitive magnetic switchpoint accuracy.
These devices use a high frequency chopper-stabilization technique, produced using the Allegro advanced BiCMOS wafer fabrication process, to achieve magnetic stability and to eliminate offset inherent in single-element devices exposed to harsh application environments.
Commonly found in a number of automotive applications, these switches are utilized in sensing seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position.
