ELECTRONIC APPARATUS

摘要

An electronic apparatus includes a first voltage detection circuit which detects when a voltage, becomes higher than a first level after the voltage starts to be supplied to a peripheral circuit, and detects when the voltage becomes lower than a second level after a supply of the voltage to the peripheral circuit starts to be interrupted, and a second voltage detection circuit which detects when the voltage becomes lower than a reference level while the peripheral circuit operates. The second level is lower than the reference level.

1. An electronic apparatus, comprising;
a voltage supply unit configured to supply a voltage to an internal node based on a level of a power supply voltage; an output unit configured to output a voltage detection signal according to a voltage level of the internal node; and a voltage control unit configured to control the voltage of the internal node by changing a resistance value of a resistance unit connected between the internal node and a ground terminal in response to the voltage detection signal of the output unit.
