Additionally, Allegro offers a sleep mode logic level input that disables the A3987 and reduces the supply currents to less than 120mA, as well as a disable logic level input that disables the output drivers without putting the A3987 into the sleep mode. To further the A3987’s flexibility and reliability, there is an over-current/short circuit current protection feature that protects the internal output MOSFETs from shorts between motor leads and motor leads to ground.
