Description
Technical field
The present invention relates to server current protection technology.
Background technology
In server board normal work, its supply current is within the scope of certain.And when circuit has short circuit, electricity
During the problems such as sub- device failure, power supply supply current can be higher than normal value.In order to short circuit, electronic device damage etc. occur in circuit
Equipment is protected during problem, power module is typically provided overcurrent protection function.Preset OCP（Over current
Protection, overcurrent protection）Parameter, when electric current exceedes the parameter, closes the output of power down source.
Current OCP parameters are set by way of the external specific valued resistor of power module, and resistance and OCP parameters are present
One-to-one relation.In existing design, fixation more than external resistance can not be adjusted on circuit boards.
In the design of server board, in order to improve compatibility, a variety of different business plates can be connect by having 1 power supply board
The situation of card.Different business board khaki internal circuit, function are variant, cause current range during its normal work to have difference
It is different.Identical OCP parameters are set if them, are unfavorable to server reliability.
The content of the invention
The present invention is solution above-mentioned technical problem.Therefore, the present invention provides a kind of server adaptive overcurrent protection circuit
And adaptive approach, it, which has, to carry out type identification to inserted business board card by power supply board, according to business board Card Type,
Switch the advantage for the OCP parameter setting resistance being connected on power module by on-off circuit.
To achieve these goals, the present invention is adopted the following technical scheme that.
A kind of server adaptive overcurrent protection circuit, business board is connected with power supply board；Power supply board is provided with electricity
Source module, gate-controlled switch circuit, gate-controlled switch circuit are connected with multiple configuration resistance；Transmitted between business board and power supply board
Board recognizes signal, and board identification signal transmission direction is from business board to power supply board；On power supply board, board identification
Signal is linked on gate-controlled switch circuit；Gate-controlled switch circuit can recognize the level of signal according to board, according to default correspondence
Relation, corresponding configuration resistance is connected on power module.
Server adaptive overcurrent protection circuit adaptive approach, when business board is connected with power supply board, board is known
Level signal is transferred on the gate-controlled switch circuit of power supply board through business board.Gate-controlled switch circuit recognizes signal according to board
Level, according to default corresponding relation, corresponding configuration resistance is connected on power module.
Beneficial effects of the present invention：The present invention is directed in server design, in the case of compatible many boards, to different plates
Card sets the demand of different OCP parameters to be designed.Type identification is carried out to inserted business board card by power supply board, according to industry
Business board type, the OCP parameter setting resistance being connected on power module is switched by on-off circuit, so as to change OCP settings
Value.The design sets different OCP parameters for different boards, can improve the validity of power supply overcurrent protection function and reliable
Property.
