Description
The A1184 device is a standard, two-wire, unipolar, Hall effect
switch. 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 device is 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 A1184 is 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 than the more traditional open-collector output
switches. Additionally, the system designer gains inherent
diagnostics because output current normally flows in either
