UTC U651 LINEAR INTEGRATED CIRCUIT
SINGLE OUTPUT HALL EFFECT LATCH
GENERAL DESCRIPTION
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.
