General Description

GND

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.

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℃, 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.
