General Description
AH280 is the integrated Hall sensor owned two
complementary outputs for motor’s coil driving, auto
locked shutdown and auto restart functions.
Functional block diagram includes that a regulator
with
temperature-compensated
on-chip Hall voltage generator, a comparator, a
Schmitt trigger and two current output drivers. The
regulator can provide wide operational voltage
range. The Hall voltage generator is to amplify the
Hall voltage due to Hall effect. A Schmitt trigger is
to provide switching Hysteresis for noise rejection.
To avoid coil burning, rotor-lock detection circuit will
shutdown the output driver if detect rotor-lock status.
A rotation recovery circuit is to restart the motor
after rotor-lock is removed. In addition, the auto
re-start time is flexible by adjusting the capacitance
(C
T
).
