General Description

The SS2509-R is a bipolar Hall effect sensor IC fab-

ricated from mixed signal CMOS technology. The

device integrates a voltage regulator, Hall sensor with

dynamic offset cancellation system, Schmitt trigger

and an output driver with internal pull-up resistor, 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 Thin Small Outline Transistor (TSOT) for surface mount process or in a Plastic Single

In Line (SIP 3L flat) for through- hole mount. Both 3-lead packages are RoHS compliant.
