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.
