General Description
The SS2309 is a Hall-effect sensor IC fabricated from mixed signal CMOS technology. The device integrates 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 ...
