General Description
The SS2509 is a bipolar Hall effect sensor IC fabri-
cated from mixed signal CMOS technology. The de-
vice 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 Small Outline Transistor (SOT) 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.
