Abstract
A control circuit including a timer circuit and a voltage monitor circuit is provided. The timer circuit enables a trigger signal every a fixed time interval in response to a wake-up event. The voltage monitor circuit is configured to determine whether the operation voltage reaches the expected voltage and includes a signal-generating circuit, a first delay circuit, a second delay circuit, and a determination circuit. The signal-generating circuit generates a reference signal according to the trigger signal. The first delay circuit receives the operation voltage and delays the reference signal to generate a first delay signal. The second delay circuit delays the trigger signal to generate a second delay signal. The determination circuit enables a wake-up signal according to the reference signal, the first delay signal, and the second delay signal in response to the wake-up event.
