Unipolar Hall-Effect Digital Switch
General Descriptions
The SS1068 is a unipolar Hall-effect sensor IC fab-
ricated from bipolar technology. The device inte-
grates a voltage regulator, reverse battery protec-
tion diode, Hall sensor with dynamic offset can-
cellation system, temperature compensation cir-
cuitry, 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.
peratures to +150°C,and are more stable with both
temperature and supply voltage changes. The uni-
polar switching characteristic makes these devices
ideal for use with a simple bar or rod magnet.
Thanks to its wide operating voltage range and ex-
tended choice of temperature range, it is quite suit-
able for use in automotive, industrial and consumer
applications.
The device is delivered in a Small Outline Transis-
tor (SOT) or in a Plastic Single In Line (SIP 3L
flat). Both 3-lead packages are RoHS compliant.
These Hall-effect switches are monolithic integrat-
ed circuits with tighter magnetic specifications, de-
signed to operate continuously over extended tem-

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)
