A1180/81/82/83

Sensitive Two-Wire Field-Programmable Chopper-Stabilized

Unipolar Hall-Effect Switches

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

Package LH, 3-pin SOT

accounting for variations 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 A1180-83 family of devices are 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

A1180-83 family of devices 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 currents of the A1181 and A1183 switch ^HIGHin the presence of a south

polarity magnetic ﬁeld of sufﬁcient strength; and switch LOW otherwise, including

when there is no signiﬁcant magnetic ﬁeld present. The A1180 and A1182 have

inverted output current levels: switching LOW in the presence of a south polarity

magnetic ﬁeld of sufﬁcient strength, and HIGH otherwise. The devices also differ in

their speciﬁed LOW current supply levels.

ABSOLUTE MAXIMUM RATINGS

Supply Voltage, V_CC..........................................28 V

Reverse-Supply Voltage, V_RCC........................–18 V

Magnetic Flux Density, B .........................Unlimited

Operating Temperature

Ambient, T_A, Range E..................–40ºC to 85ºC

Ambient, T_A, Range L................–40ºC to 150ºC

Maximum Junction, T_J(max)........................165ºC

Storage Temperature, T_S..................–65ºC to 170ºC

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.

Factory-programmed versions are also available. Refer to: A1140, A1141, A1142,

A1143, A1145, and A1146.
