| 发明名称 | Electronic apparatus detecting power supply voltage using different levels | ||
| 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. | ||

| 主权项 | 1. An electronic apparatus, comprising: a first voltage detection circuit suitable for detecting when a voltage increases to become higher than a first level after the voltage starts to be supplied to a peripheral circuit and detecting when the voltage decreases to become lower than a second level, which is lower than the first level, after a supply of the voltage to the peripheral circuit starts to be interrupted; and a second voltage detection circuit suitable for detecting when the voltage decreases to become lower than a reference level while the peripheral circuit operates, wherein the second level is lower than the reference level. | ||
