The SS2881 is a Hall-effect sensor IC fabricated from

mixed signal CMOS technology. The device inte-

grates a voltage regulator, Hall sensor with dynamic

offset cancellation system, Schmitt trigger and an

open-drain output driver, all in a single package.

It incorporates advanced chopper stabilization techniques to provide accurate and stable magnetic switch points.

There are many applications for this HED - Hall Electronic Device - in addition to those listed above. The design,

specifications and performance have been optimized for commutation applications in 5V and 12V brushless DC

motors.

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) for surface mount process or in a Plastic Single In

Line (TO92) for through- hole mount. Both 3-lead packages are RoHS compliant.
