Abstract
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 () and a set time period memory () 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 () and a power supply apparatus cost is reduced correspondingly.
