General Description

Hall

Plate

The SS189 is a unipolar Hall-effect sensor IC

fabricated from bipolar technology. The device

integrates a voltage regulator, reverse battery protection

diode, Hall sensor with dynamic offset cancellation

system, temperature compensation circuitry, small

signal amplifier, Schmitt trigger and an open-collector

output to sink up to 25 mA. With suitable output pull

up, they can be used with bipolar or CMOS logic

circuits.

GND

SIP Package

Pin 1 – V_DD

Pin 2 – GND

Pin 3 – OUT

SOT Package

Pin 1 – V_DD

Pin 2 – OUT

Pin 3 – GND

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to

operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply

voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod

magnet.

Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in

automotive, industrial and consumer applications.

The device is delivered in a Small Outline Transistor (SOT) or in a Plastic Single In Line ( SIP 3L flat). Both 3-lead

packages are RoHS compliant.
