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.
