Data Sheet
General Description
The AH477A is an integrated Hall sensor with H-
bridged output driver designed for brushless DC motor
applications. The device includes an on-chip Hall sen-
sor for magnetic sensing, an amplifier that amplifies
the Hall voltage, a comparator to provide switching
hysteresis for noise rejection, a bi-directional drivers
for sinking and driving large current load. It also
includes an internal bandgap regulator to provide tem-
perature compensated bias for internal circuits and
allows a wide operating supply voltage range.
Placing the device in a variable magnetic field, if the
magnetic flux density is larger than threshold BOP, the
DO is turned to sink and DOB is turned to drive. This
output state is held until the magnetic flux density
reverses and falls below BRP, then causes DO to be
turned to drive and DOB turned to sink.
The AH477A is available in TO-94 (SIP-4L) package.
