摘要： Provided is a power supply switching circuit with a smaller circuit scale. When a detector (11) detects that a voltage (V1) as an input power supply voltage is higher than a detection voltage (VDET), a control circuit (41) operates with a voltage (V4) output from a diode OR circuit (42), supplies a voltage (V2) as an input power supply voltage to a gate of a PMOS transistor (17), supplies a voltage (V3) to a gate of a PMOS transistor (18), and supplies a ground voltage to a gate of a PMOS transistor (19). Then, the PMOS transistors (17 and 18) are turned OFF and the PMOS transistor (19) is turned ON. In this case, the voltage V1 of a first terminal (T1) is output from a third terminal (T3) as the voltage (V3), which is an output power supply voltage.

摘要： Provided are a voltage application time period measuring circuit which does not require a battery, and a power supply apparatus including the voltage application time period measuring circuit. Each of a voltage application time period memory (32) and a set time period memory (33) is a nonvolatile memory, and hence it is unnecessary to provide a battery for holding information stored in each of the memories in the outside of the voltage application time period measuring circuit (30) and a power supply apparatus cost is reduced correspondingly.
