Abstract
A low voltage DC one-shot circuit momentarily increases the voltage applied by a NiCad battery pack to the gate of a MOSFET. A charge pump generates a supply voltage to a monostable multivibrator which is manually actuated by a switch to emit an output pulse of fixed amplitude and pulse width. The pulse is passed through a level shift network where it is summed with a bias voltage for application to the gate of the MOSFET.
