Hard disk hot Atach & Detach power supply protection circuit of computer device

Abstract

A power supply protection circuit of hot connect - disconnect for computer hard disc consists of a hard disc connect - disconnect detection circuit connected to detected hard disc for checking whether hard disc is connected on computer properly or not and supplying operation power to hard disc if it is, a current detection circuit connected to power supply wire for checking whether current loaded on wire is over preset current value or not, a over current protection circuit for generating over current protection signal to switch off power supply to hard disc when current on wire is over preset current value.

Description

【Technical field】 [0001] The invention relates to a hard disk protection circuit of a computer device, in particular to a hard disk hot-swappable power supply protection circuit of a computer device. 【Background technique】 [0002] A computer device mainly includes various input devices, output devices, data storage devices, interface circuits, processing units and other components. Among them, the hard disk is an important data storage device. All user data, programs, and configuration files All other data need to be stored in the hard disk. [0003] Due to the increasing computer technology, consumers have higher and higher requirements for computer functions. Therefore, in the design of many computer modules, there are detachable or hot-swappable designs. In terms of hard disk products, there are also various functional designs. For example, some manufacturers design the hard disk into a detachable structure, so that the user can easily take the hard disk out of the dra...
