Description
The A1190, A1192, and A1193 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. 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 A119x 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 two 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. Both packages are
lead (Pb) free, with 100% matte tin leadframe plating.
