ためのコンピュータに読み込ませるインターフェイス回
路とを備えた電源バックアップ装置。A diode connected in series to the power line that supplies power to the load,
A first resistor and a large-capacity capacitor connected in series between the connection point between this load and the diode and the ground detect that this charging voltage has fallen below a reference voltage obtained by dividing the voltage of the power supply line. A power backup device comprising: a comparator that outputs a voltage drop signal when the voltage drop signal is applied; and an interface circuit that reads the voltage drop signal into a computer for determining whether a power backup operation for the load has been correctly executed.
