AH280 is an integrated Hall sensor that has two complementary outputs for driving motor coils, auto-locked shutdown and auto-restart functions. Functional block diagram includes a temperature-compensated bandgap regulator, 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, and automatically restart.
