SS732/SS632
Hall Latch - High Sensitivity
General Description
The S732 is a bipolar 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 output driver with internal pull-up resistor,
all in a single package. It incorporates advanced chopper
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.
