Abstract: An electronic fuse based-protection circuit system, including a plurality of electronic fuse based-protection circuits, where each electronic fuse based-protection circuit is electrically connected to a power supply and a load through an input terminal and an output terminal respectively and includes a sampling resistor, a MOSFET switch, and a logic control branch circuit. The sampling resistor is electrically connected to the input terminal and has a sampling terminal. The MOSFET switch is electrically connected to the sampling terminal and the output terminal. The logic control branch circuit obtains a sampling voltage of the sampling resistor between the input terminal and the sampling terminal and an on-off judging voltage by amplifying the sampling voltage. When the on-off judging voltage is greater than a reverse-bias voltage of the logic control branch circuit, an off signal is then transmitted to the MOSFET switch, to turn off the MOSFET switch.
