A fully integrated circuit configuration that can be used to control the power path of a pair of PMOS load switches is described. The circuit also integrates a programmable slew rate for the second PMOS load switch in order to control the power path from the input system voltage (battery or power supply) or from a backup source of power. The integrated circuit configuration also contains a charge pump circuit which can be used to charge the backup source of power to a voltage that is greater than the input voltage.
