Abstract:
1. A power control circuit comprising: a common node coupled to a first terminal via a first switch and coupled to a second terminal via a second switch, said first switch having a first body diode, and said second switch having a second body diode; a switching node coupled to said common node via a third switch and coupled to a reference terminal via a fourth switch, said third switch having a third body diode, and said fourth switch comprising a diode; and a controller coupled to said first, second, third and fourth switches and operable for controlling said first, second, third and fourth switches to control power flow between said first terminal, said second terminal, said common node, and said switching node, wherein cathodes of said first, second and third body diodes are coupled to said common node, and a cathode of said diode of said fourth switch is coupled to an anode of said third body diode, and wherein resistance between said common node and the cathode of each body diode of said first, second and third body diodes is substantially equal to zero.
