Description
The A1152, A1153, A1155, and A1156 comprise a family of
two-wire, unipolar, Hall-effect switches, which are factory-
trimmed to optimize magnetic switchpoint accuracy. These
devices are produced on the Allegro advanced BiCMOS
wafer fabrication process, which implements a patented high
frequency, 4-phase, chopper-stabilization technique. This
technique achieves magnetic stability over the full operating
temperature range, and eliminates offsets inherent in devices
with a single Hall element that are exposed to harsh application
environments.
The A115x family has a number of automotive applications.
These include sensing seat track position, seat belt buckle
presence, hood/trunk latching, and shift selector position.
Two-wire unipolar switches are particularly advantageous in
cost-sensitive applications because they require one less wire
for operation versus the more traditional open-collector output
switches. Additionally, the system designer inherently gains
diagnostics because there is always output current flowing,
which should be in either of two narrow ranges. Any current
level not within these ranges indicates a fault condition.
