Abstract

The invention discloses a server-adaptive overcurrent protection circuit. A business board card is connected with a power supply board card; a power module and a controllable switch circuit are arranged on the power supply board card; the controllable switch circuit is connected with a plurality of configuration resistors; a board card identification signal is transmitted between the business board card and the power supply board card; the transmission direction of the board card identification signal is from the business board card to the power supply board card; on the power supply board card, the board card identification signal can be accessed to the controllable switch circuit; and the controllable switch circuit is capable of connecting a corresponding configuration resistor onto the power module according to a level of the board card identification signal and a preset corresponding relationship. According to the server-adaptive overcurrent protection circuit, type identification is carried out on an inserted business board card through the power supply board card; and according to the type of the business board card, OCP parameter setting resistor connected on the power module is switched through the switch circuit, so as to change an OCP set value. According to the server-adaptive overcurrent protection circuit, different OCP parameters are set for different board cards, so that the effectiveness and reliability of a power overcurrent protection function can be improved.

Description

technical field [0001] The invention relates to server overcurrent protection technology. Background technique [0002] When the server board works normally, its power supply current is within a certain range. And when there is a short circuit in the circuit, damage to electronic devices, etc., the power supply current will be higher than the normal value. In order to protect the equipment when there are problems such as short circuit and electronic device damage, the power module generally has an overcurrent protection function. That is, the OCP (Over current protection, over-current protection) parameter is preset, and when the current exceeds this parameter, the power output is turned off. [0003] At present, the OCP parameters are set by externally connecting the power module with a specific resistance resistor, and there is a one-to-one correspondence between the resistance value and the OCP parameter. In the existing design, most of the external resistors are fixed...
