A1180, A1181, A1182, and A1183

Sensitive Two-Wire Field-Programmable Chopper-Stabilized

Unipolar Hall-Effect Switches

Features and Benefits

▪ Chopper stabilization

Description

The A1180, A1181, A1182, and A1183 devices are sensitive,

two-wire,unipolar,Halleffectswitches.Theoperatepoint,B_OP,

can be field-programmed, after final packaging of the sensor

and placement into the application. This advanced feature

allows the optimization of the sensor switching performance,

by effectively accounting for variations caused by mounting

tolerances for the device and the target magnet.

▫ Low switchpoint drift over operating

temperature range

▫ Low sensitivity to stress

▪ Field programmable for optimized switchpoints

▪ On-chip protection

▫ Supply transient protection

▫ Reverse-battery protection

▫ On-board voltage regulator

▫ 3.5 to 24 V operation

This family of devices are produced on the Allegro

MicroSystems advanced BiCMOS wafer fabrication process,

which implements a patented, high-frequency, chopper-

stabilization technique that achieves magnetic stability and

presence, hood/trunk latching, and shift selector position.

Two-wire unipolar switches are particularly advantageous

in price-sensitive applications, because they require one

less wire than the more traditional open-collector output

Packages: 3 pin SOT23W (suffix LH), and

3 pin SIP (suffix UA)
