General Description
The SS1348 is a unipolar Hall-effect sensor IC fabri-
cated from CMOS technology. The device integrates a
voltage regulator, Hall sensor with dynamic offset can-
cellation 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 oper-
ate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply volt-
age changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod mag-
net.
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) and in a Plastic Single In Line ( SIP 3L flat). Both
3-lead packages are RoHS compliant.
