General Description
The SS441 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.
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.
