Embodiment Construction

[0024] see first figure 1 As shown, the hard disk hot-swappable power supply protection circuit of the computer device of the present invention can supply working power to the hard disk after confirming that the hard disk has been properly plugged into the computer device, and can detect that the hard disk is overloaded. , the working power supplied to the hard disk can be cut off in time to protect the hard disk and further ensure the normal operation of the entire computer device.

[0025] In the current design of computer devices, the working power used by the hard disk includes +12V and +5V working power, so the power supply 1 in the computer device supplies the +12V and +5V respectively through the power supply lines L1 and L2. The working power supply to the hard disk 2.

[0026] figure 1 In the shown functional block of the circuit, the hard disk hot swap power protection circuit of the present invention includes a first power supply switch unit 41 connected in series...

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...
