SS443
Unipolar Hall-Effect Digital Switch
General Description
The SS443 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.
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.
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
Glossary of Terms
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.
