Abstract: An electric circuit for powering a load using an IPD includes a charge pump and a comparator. A first conductive path connects the charge pump to a positive node of the comparator. A second conductive path connects the battery to a negative node of the comparator and is also connected to a ground. A third conductive path connecting an output of the comparator to the IPD. A second diode is disposed on the third conductive path with the anode connected to the IPD and the cathode connected to an output of the comparator. The comparator generates a low output signal when the charge pump voltage is less than the battery voltage so as to provide a path for current from the battery to flow through the first diode into the output of the comparator and to the ground.
