Abstract
An electronic device including a voltage detection circuit, a control and protection circuit, at least one voltage converter, and a system-on-chip is provided. The voltage detection circuit detects a voltage source to output a voltage detection signal. The control and protection circuit, coupled to the voltage detection circuit, generates a system power enabling signal according to the voltage detection signal. The at least one voltage converter, coupled to the control and protection circuit, generates a system power signal according to the system power enabling signal. The system-on-chip, coupled to the at least one voltage converter, controls the electronic device when receiving the system power signal. In response to a power off signal generated from the system-on-chip, the control and protection circuit further isolates the voltage detection signal to avoid the transition of the voltage detection signal affecting a system shutdown procedure of the electronic device.
