摘要:
A motor drive circuit operates in a first mode in which the output current flowing to a first output terminal from a second output terminal is increasing or in a second mode in which the output current flowing to the first output terminal from the second output terminal is decayed. In the first mode, a first voltage signal is output from the first signal terminal and the ground voltage output from the second signal terminal and, in the second mode, a ground voltage is output from the first signal terminal and a second voltage signal is output from the second signal terminal. The motor drive circuit compares the signals output from the first and second signal terminals and output comparison results to a control unit for controlling the output current through the motor coil.
