Abstract

The invention discloses a RAID card power supply circuit, which comprises a PMOS transistor, a current detection unit and an operation unit. The D terminal of the PMOS transistor is connected with a current detection unit, the S terminal of the PMOS transistor is connected with the standby unit in the power-down protection circuit of the RAID card, the G terminal of the PMOS transistor is connected with the output terminal of the OR arithmetic unit, or the input end of the operation unit is respectively connected with the output end of the current detection unit and the output end of the power-down detection unit in the power-down protection circuit, The current detection unit is arranged between the power standby unit and the RAID card, and is used for outputting a high level to control the PMOS transistor to be turned off if it is judged that the line between the power standby unit and the RAID card is overcurrent during the power supply of the power standby unit to the RAID card. The over-current damage to the standby unit can be avoided, and the body diode contained in the PMOS transistor can be utilized 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), more specifically, to a power supply circuit for a RAID card. Background technique [0002] With the rapid development of the Internet, the continuous rise of cloud computing technology, and the continuous increase of online business volume, higher requirements are put forward for the data processing capability and storage capacity of the server in the computer room. In order to expand the storage capacity of the server system and improve the performance of data reading and writing, a RAID card is generally used to form a disk array with multiple hard disks in the server system by doing RAID0, RAID5, etc. to expand the read and write capabilities of disk data. performance and storage capacity. [0003] With the development of cloud computing and big data, businesses of all walks of life are migrating to the Internet cloud. Once a large-sca...
