General Description

The SS159 is a unipolar Hall-effect sensor IC fabricat-

ed 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.
