DESCRIPTION
The A119x and A119x-F comprise a family of two-wire,
unipolar, Hall-effect switches, which can be trimmed by the
user at end-of-line to optimize magnetic switchpoint accuracy
in the application. The latter (-F option) are temperature-
compensated for use with ferrite magnets. These devices are
produced on theAllegroadvanced 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 A119x and A119x-F 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.
All family members are offered in three package styles. The LH
is a SOT-23W style, miniature, low-profile package for surface-
mount applications. The UA is a 3-pin, ultra-mini, single inline
package (SIP) for through-hole mounting. The UB is a 2-pin single
inline package (SIP) for through-hole mounting that integrates
the power supply decoupling capacitor. All three packages are
lead (Pb) free, with 100% matte-tin leadframe plating.
