A1184

Standard Two-Wire Field-Programmable Chopper-Stabilized

Unipolar Hall-Effect Switches

Features and Benefits

▪ Chopper stabilization

Description

TheA1184 device is a standard, two-wire, unipolar, Hall effect

switches. The operate point, 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

Packages: 3 pin SOT23W (suffix LH), and

3 pin SIP (suffix UA)

Two-wire unipolar switches are particularly advantageous

in price-sensitive applications, because they require one

less wire than the more traditional open-collector output

switches. Additionally, the system designer gains inherent

diagnostics because output current normally flows in either
