SS5781
Unipolar Hall Switch-Low Sensitivity
General Description
The SS5781 is a unipolar Hall-effect sensor IC fabricated
from CMOS technology. The device integrates a voltage
regulator, Hall sensor with dynamic offset cancellation
system, small signal amplifier, Schmitt trigger and an
open-drain output driver. 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.
