A1184

Standard Two-Wire Field-Programmable Chopper-Stabilized

Unipolar Hall-Effect Switches

The A1184 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 optimiza-

tion of the sensor switching performance, by effectively accounting for variations

Package LH, 3-pin SOT

caused by mounting tolerances for the device and the target magnet.

1. VCC

2. No connection

3. GND

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 eliminates

the offsets that are inherent in single-element devices exposed to harsh applica-

tion environments. Commonly found in a number of automotive applications, the

A1184 is utilized to sense: seat track position, seat belt buckle presence, hood/

trunk latching, and shift selector position.

Package UA, 3-pin SIP

Two-wire unipolar switches are particularly advantageous in price-sensitive appli-

cations, because they require one less wire than the more traditional open-collec-

tor output switches. Additionally, the system designer gains inherent diagnostics

because output current normally flows in either of two narrowly-specified ranges.

Any output current level outside of these two ranges is a fault condition. The

A1184 also features on-chip transient protection, and a Zener clamp to protect

against overvoltage conditions on the supply line.

1. VCC

2. GND

3. GND

The output current of the A1184 switches ^HIGHin the presence of a south polarity

magnetic field of sufficient strength; and switches LOW otherwise, including when

there is no significant magnetic field present.

Both devices are offered in two package styles: LH, a SOT-23W miniature low-

profile package for surface-mount applications, and UA, a three-lead ultramini

Single Inline Package (SIP) for through-hole mounting. Each package is available

in a lead (Pb) free version (suffix, –T) with 100% matte tin plated leadframe.
