Abstract:
1. An over-current protection system applied for a computer system, wherein the computer system comprises a current supply module, a processor and a battery; the over-current protection system commands the processor to disable its boost state if a first current generated by the current supply module under a boost state enabled by the processor becomes greater than a second current affordable by the current supply module; the over-current protection system comprising: a charge module electrically connected to the current supply module for charging the battery, and the charge module comprises a detection element used for detecting the first current generated by the current supply module under the boost state, and if the first current becomes greater than the second current affordable by the current supply module, the charge module stops charging and generates a signal; and a protection circuit electrically connected to the charge module; when the processor enables the boost state such that the first current increases and becomes greater than the second current affordable by the current supply module, the protection circuit will transmit the signal generated by the charge module to the processor, to command the processor to disable the boost state.
