A system for controlling slew rate in a motor control circuit for a motor comprises a high side switching device coupled to a coil of the motor, the high side switching device operable to control a voltage excitation signal applied at the coil. The system also comprises a high side slew rate control circuit operable to control a slew rate of the voltage excitation signal. The high side slew rate control circuit includes: an amplifier having an output coupled to an input of the high side switching device, a current sink coupling a first input of the amplifier to ground, a capacitor further coupling the first input of the amplifier to ground, and a feedback path from an output of the high side switching device to a second input of the amplifier.
