Abstract
An over-current protection device is provided. A first end of a first resistor is coupled to a voltage input terminal and a second end of the first resistor is coupled to a control terminal of an electronic switch. A detecting pin of a control chip is coupled to the second end of the first resistor and an input pin of the control chip is coupled to the first end of the first resistor. A control pin of the control chip is coupled to a control terminal of the electronic switch. The voltage output terminal is coupled to a first terminal of the electronic switch. The control chip compares a preset current value saved therein with a detecting current passing through the first resistor. If the detecting current is greater than the preset current value, there is no voltage output from the voltage output terminal.
