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

▫ Supply transient protection

▫ Reverse battery protection

▫ On-board voltage regulator

▫ 3.0 to 24 V operation

▪ Solid-state reliability

TheA1150,A1152,A1153,A1155,A1156,A1157, andA1158

comprise a family of two-wire, unipolar, Hall-effect switches,

which are factory-trimmed to optimize magnetic switchpoint

accuracy.ThesedevicesareproducedontheAllegro®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.

▪ Robust EMC and ESD performance

▪ Industry leading ISO 7637-2 performance through use of

proprietary, 40-V clamping structures

The A115x 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.
