Abstract
An apparatus for power source protection with automatic latch-off is provided for use in an electronic apparatus. The electronic apparatus includes a power supply and a main functional circuit, such as a notebook computer. The power supply is coupled to the main functional circuit via an electronic switching device, so as to power the main functional circuit via a power source terminal of the electronic switching device. The apparatus for power source protection with automatic latch-off includes a low-voltage-triggered latch-off device and a low-voltage-triggered responding device. The low-voltage-triggered latch-off device is coupled to the electronic switching device, so as to control the on or off state of the electronic switching device. The low-voltage-triggered responding device is coupled to the power source terminal and the low-voltage-triggered latch-off device. When a short circuit occurs, the low-voltage-triggered responding device can enable the latch-off device to turn off the electronic switching device, so as to cut off the power supply to the main functional circuit.
