Abstract

The invention discloses a RAID card power supply circuit, which comprises a PMOS tube, a current detection unit and an OR operation unit; the D terminal of the PMOS tube is connected with the current detection unit, and the S terminal of the PMOS tube is connected with the power-down protection of the RAID card The backup power unit in the circuit is connected, the G terminal of the PMOS transistor is connected to the output terminal of the OR operation unit, or the input terminal of the operation unit is respectively connected to the output terminal of the current detection unit and the output of the power failure detection unit in the power failure protection circuit The current detection unit is set between the backup power unit and the RAID card. It is used to determine that the line between the backup power unit and the RAID card is over-current when the backup power unit is supplying power to the RAID card. Output high level to control the PMOS tube to turn off. The damage to the backup power unit due to overcurrent can be avoided, and the body diode contained in the PMOS tube can be used to realize the anti-leakage function.

Description

Technical field [0001] The present invention relates to the technical field of RAID (Redundant Arrays of Independent Disks, Disk Array), and more particularly to a RAID card power supply circuit. Background technique [0002] With the rapid development of the Internet, cloud computing technology is constantly increasing, online traffic is increasing, and the data processing capabilities and storage capacity of computer room servers have put forward higher requirements. In order to expand more storage capacity in the server system, improve the performance of the data read and write, generally use the RAID card to form a disk array in the server system by making RAID0, RAID5, etc. to expand the disk data read and write. Performance and storage capacity. [0003] With the development of cloud computing, big data, the business of all walks of life is migrated to the Internet cloud. Once the power grid is powered on, the real-time information on the disk array on the server system wil...
