SINGLE OUTPUT HALL EFFECT LATCH
The UTC U651 is a Integrated Hall sensor with latch designed for electronic commutation of brushless DC
motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a
comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for
noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature
compensated supply voltage for internal circuits and allows a wide operating supply range.
*3.5V to 20V operation
*On-chip Hall sensor with two different sensitivity and hysteresis settings.
*Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range.
*Open-Collector 25mA Output.
*Reverse Polarity Protection.
