  • Electronic device and over-current protection circuit thereof
    Patent number: 9906011
    Abstract: An over-current protection circuit includes a first connector, a first current measuring unit, a first switch unit, a first resistor unit, and a second connector. The first connector is electrically coupled to a power supply unit (PSU). When a current of the first resistor unit measured by the first current measuring unit is less than a first reference value, the first switch unit is turned on, and the second connector receives a first power supply from the PSU. When the current of the first resistor unit measured by the first current measuring unit is greater than or equal to the first reference value, the first switch unit is turned off, and the second connector does not receive the first power supply from the PSU.
