Electronic apparatus for stopping supply of power to load during voltage detection operation |
摘要 |
An electronic apparatus which controls the driving of a load circuit in accordance with a detected feed power voltage. The feed power voltage can be accurately detected even when it is low. In order to achieve this, the apparatus in one embodiment includes a power feed unit, a boosting circuit for increasing a voltage of the supply power, a voltage detecting circuit for detecting the voltage of the supply power as increased by the boosting circuit and outputting a voltage detection signal, and the load circuit which is driven based on the supply power. A voltage detection circuit detects the supply voltage only when it is not being used to drive the load circuit.
