TL;DR: In this paper, the potentials at the first and second nodes are compared with each other by a voltage comparator (10) connected between the output node (3) and ground.
Abstract: A first node (1) is connected to an external power source (21) via a switch (21). A second node (2) is connected to an internal power source (22) whose voltage is lower than that of the external power source (21). The first and second nodes (1, 2) are connected to an output node (3) via first and second MOSFET switches (7, 8). The output node (3) is connected to a semiconductor circuit (24). The potentials at the first and second nodes (1, 2) are compared with each other by a voltage comparator (10) connected between the output node (3) and ground. A MOSFET (32) is quickly turned on and off in response to the potential at the first node (1).
