ABSTRACT:
A circuit for controlling the slew rate at a motor coil during turn-on in a commutation sequence is disclosed. The disclosed circuit includes a comparator for comparing the output of error amplifier to the input of the input buffer amplifier. The comparator connects the output of the error amplifier to the input of the buffer amplifier only after the input has been charged at a controlled rate. The integrating buffer amplifier includes an amplifier with a feedback capacitor, and a current source connected at its input, for reducing the voltage slew rate during turn-on of the transistor.
