A1190, A1192, and A1193

Programmable, Chopper-Stabilized, Two Wire Hall-Effect Switches

Features and Benefits

Description

▪ High speed, 4-phase chopper stabilization

▫ Low switchpoint drift throughout temperature range

▫ Low sensitivity to thermal and mechanical stresses

▪ On-chip protection

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.

▫ Supply transient protection

▫ Reverse battery protection

▪ On-board voltage regulator

▫ 3.0 to 24 V operation

▪ Solid-state reliability

▪ Robust EMC and ESD performance

▪ Field programmable for optimized switchpoints

▪ Industry leading ISO 7637-2 performance through use of

proprietary, 40-V clamping structure

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.

Packages

3-pin ultramini SIP

1.5 mm × 4 mm × 3 mm

(suffix UA)

3-pin SOT23-W

2 mm × 3 mm × 1 mm

(suffix LH)

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

isaSOT-23Wstyle,miniature,lowprofilepackageforsurface-

mount applications.The UAis 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.
