Unipolar Hall-Effect Digital Switch
General Description
The SS443 is a unipolar Hall-effect sensor IC fabricated
from bipolar technology. The device integrates a volt-
age regulator, reverse battery protection diode, Hall
sensor with dynamic offset cancellation system, tem-
perature 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.
+150°C,and are more stable with both temperature and
supply voltage changes. The unipolar switching charac-
teristic makes these devices ideal for use with a simple
bar or rod magnet.
Thanks to its wide operating voltage range and extend-
ed 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.
These Hall-effect switches are monolithic integrated
circuits with tighter magnetic specifications, designed to
operate continuously over extended temperatures to
Glossary of Terms
MilliTesla (mT), Gauss Units of magnetic flux density: 1mT = 10 Gauss
RoHS Restriction of Hazardous Substances
Operating Point (BOP) Magnetic flux density applied on the branded side of the package which turns the output
driver ON (VOUT = VDSon
)
Release Point (BRP)
Magnetic flux density applied on the branded side of the package which turns the output
driver OFF (VOUT = high)
