COMPLEMENTARY OUTPUT HALL EFFECT LATCH
General Description
Features
Data Sheet
AH276
The AH276 is an integrated Hall sensor with output
driver 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 tem-
perature compensation circuit to compensate the tem-
perature drift of Hall sensitivity 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.
· On-Chip Hall Sensor
· 3.5V to 16V Supply Voltage
· 350mA (avg) Output Sink Current
· Reversed Supply Voltage Protection
· Build in Over Temperature Protection Function
· -20oC to 85oC Operating Temperature
· Low Profile TO-94 (SIP-4L) Package
· ESD Rating: 300V (Machine Model)
Applications
Placing the device in a variable magnetic field, if the · Dual-Coil Brushless DC Motor
magnetic flux density is larger than threshold BOP, the
pin DO will be turned low (on) and pin DOB will be

magnetic flux density reverses and falls below BRP,
then causes DO to be turned high (off) and DOB
turned low (on).
AH276 is available in TO-94 (SIP-4L) package.
