General Description
ATS177 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 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)。
