GENERAL DESCRIPTION
MA177H 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-collector output. An internal
band-gap 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, OUT is turned on(low). The output
state is held until a magnetic flux density reversal falls below Brp causing OUT to be turned
off (high).
