General Description
The SS1350 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°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.
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.
