Abstract
A power controller (30) comprising a plurality of MOSFET transistor switches (Q5, Q6, Q13, Q14) adapted to control the current flow through a load such as a DC motor (M), gated charge pump circuits (32a,b) are provided to control the conductivity of two (Q5, Q6) of the switches for applying driving voltages to the motor in response to direction defining control signals (/FWD, /REV) to control the direction of movement of the motor, the charge pump circuits are configured to provide for zero quiescent current flow.
