Data Sheet
General Description
The AH211 is an integrated Hall sensor with output
driver and frequency generator designed for electronic
commutation of brush-less 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, a temperature compensation circuit to
compensate the temperature drift of Hall sensitivity,
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.
Place the device in a variable magnetic field, while the
magnetic flux density is larger than threshold BOP, DO
will be turned on (low) and DOB (and FG) will be
turned off (high). This output state is held till the mag-
netic flux density reversal falls below BRP causing DO
to be turned off (high) and DOB (and FG) turned on
(low).
AH211 is available in TO-94 (SIP-4L) package.
