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.
