Unipolar Hall-Effect Digital Switch
General Description
The SS1103 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.
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.
These Hall-effect switches are monolithic integrated circuits
