Description
The AH278 is an integrated Hall sensor with output driver
designed for electronic commutation of brushless DC
motor applications. The device includes an on-chip Hall
sensor for magnetic sensing, an amplifier that amplifies
the Hall voltage, a Schmitt trigger to provide switching
hysteresis for noise rejection and two complementary
open-collector drivers for sinking large load current. It
also includes an internal band-gap regulator which is used
to provide bias voltage for internal circuits and allows a
wide operating supply voltage ranges.
Placing the device in a variable magnetic field, if the mag-
netic flux density is larger than threshold B
OP
, the pin DO
will be turned low (on) and pin DOB will be turned high
(off). This output state is held until the magnetic flux den-
sity reverses and falls below B
RP,
then causes DO to be
turned high (off) and DOB turned low (on).
