AH280 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 band-gap, an 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 (CT).
