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

producedontheAllegro^™advancedBiCMOSwaferfabrication

process,which implementsapatentedhigh-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.Theseincludesensingseattrackposition,seatbelt

bucklepresence,hood/trunklatching,andshiftselectorposition.

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.

Packages

All family members are offered in three package styles. The LH

is a SOT-23Wstyle, miniature, low-profile package for surface-

mount applications. The UA is a 3-pin, ultra-mini, single inline

package(SIP)forthrough-holemounting.TheUBisa2-pinsingle

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.
