POWER SUPPLY DEVICE

Abstract: a power supply device includes a first switch element, a second switch element, a third switch element, a fourth switch element, a fifth switch element, a sixth switch element, a switch transistor, a first battery element, and a second battery element. the first switch element selectively couples a first input node to a power node. the second switch element selectively couples a second input node to the power node. the switch transistor has a control terminal for receiving a control voltage, a first terminal coupled to an integrated node, and a second terminal coupled to a first output node. the third switch element selectively couples the integrated node to a first midway node. the fourth switch element selectively couples the integrated node to a second midway node. the first battery element and the second battery element are coupled to the first midway node and the second midway node.
