Abstract
A motor-driven integrated circuit comprises a PWM output unit and an overcurrent comparator coupled with the PWM output unit. The overcurrent comparator receives a detection signal and compares the detection signal with a reference value. When the detection signal is larger than the reference value, the overcurrent comparator outputs an overcurrent protection signal to control the PWM output unit enter an overcurrent protection mode.
