Application
AH3761 is an integrated Hall effect latched sensor designed for
electronic commutation of brush-less 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 drain output. An internal bandgap regulator is used to
provide temperature compensated supply voltage for internal
circuits and allows a wide operating supply range.
If a magnetic flux density larger than threshold Bop, DO is turned
on (low). The output state is held until a magnetic flux density
reversal falls below Brp causing DO to be turned off (high).
