Abstract
The present application discloses an electronic fuse circuit and a circuit system using the same. During startup operation, the circuit system using the electronic fuse circuit of the present application detects an amplitude of the load voltage by a second protection circuit, when the voltage exceeds a set second threshold signal, the electronic fuse circuit is controlled to be turned off; during normal operation, a current of a path where the electronic switch is located is monitored by a first protection circuit to prevent a current of the circuit system from overcurrent. According to the technical solution of the present disclosure, the load can be prevented from damage caused by a failure such as short circuit and electricity leakage of the switch power supply, and the system can be protected from overcurrent.
