摘要
A stepper motor control circuit having a reduced number of discrete components is provided by using an on-chip analog to digital converter of a single chip microcomputer to control the waveforms of chopped winding currents. Four power MOSFET's, four diodes and two sense resistors can be added to the circuitry of a board populated by the single chip microcomputer to implement a full step motor controller. The addition of a holding current circuit frees the computer for servicing other tasks when the motor is idle.
