    摘要: A motor-driven integrated circuit (10) comprises a multiple-time programmable memory (120) to store a motor driven program, a memory (130) having a capacity larger than or equal to a capacity of the multiple-time programmable memory (120), and a central processing unit (115). When the motor-driven integrated circuit (10) is powered or reset, the central processing unit (115) copies the driven program from the multiple-time programmable memory (120) to the memory (130).

    摘要: A motor-driven integrated circuit (10) comprises a PWM output unit (125) and an overcurrent comparator (180) coupled with the PWM output unit (125). The overcurrent comparator (180) 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 (180) outputs an overcurrent protection signal to control the PWM output unit (125) enter an overcurrent protection mode.

    摘要: A motor-driver integrated circuit comprises a plurality of position comparators (190), a timer (150) and a central processing unit (115). Each of the plurality of position comparators (190) receives a pole detection signal denoted a position of a rotor of a motor. The timer (150) receives a timing interrupt signal by the plurality of position comparators (190) when a predetermined edge of the pole detection signal is generated and records a time of the predetermined edge. The central processing unit (115) obtains a rotation speed of the motor according to a time difference between two predetermined edges.
