Description
The A1140, A1142, and A1143 devices are sensitive, two-wire,
unipolar, Hall effect switches that are factory-programmed at
end-of-line to optimize magnetic switchpoint accuracy. These
devices use a patented 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. Two-wire unipolar switches, such as the
A1140/A1142/A1143 family, are particularly advantageous in
price-sensitive applications because they require one less wire
for operation than do switches with the more traditional open-
collector output. 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. The
A1140/A1142/A1143 family of switches also features on-chip
A1140-DS, Rev. 17
