| Zusammenfassung: | A portable battery life checkup device is provided to check the remaining life of the battery by supplying a reference voltage of a constant voltage by using a shunt regulator. An operation voltage supply battery(110) supplies a direct current voltage. A shunt regulator(130) is connected to the operation voltage supply battery and outputs the reference voltage. A voltage divider(140) is connected in parallel to the shunt regulator and outputs the plurality of division voltages. An LED driving control signal is outputted in a voltage comparison unit(150). A first voltage distributor(141) outputs a first distribution voltage. A second voltage distributor(142) outputs the second distribution voltage. |
