Description
The A1185 and A1186 are ultrasensitive, two-wire, unipolar
Hall effect switches. The operate point, B
OP
, 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 new DABIC5 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 A1185 and
A1186 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 wire
