Problems solved by technology

However, in the design of the existing hard disk system, usually only the ACTIVE function is designed, and the Staggered Spin-up function is not designed on the system. Therefore, during the use of the hard disk, only the ACTIVE function can be realized instead of the ACTIVE function. Staggered Spin-up Features

Embodiment Construction

[0018] In this embodiment, a hard disk drive (HDD) is taken as an example to describe the hard disk control circuit of the present invention in detail.

[0019] Such as figure 1 As shown, it is a preferred embodiment of the hard disk control circuit 10 of the present invention, which includes a control chip U1, a connector J1 connected to the control chip U1 and the computer motherboard or backplane, and a connection between the control chip U1 and the connector J1. Between the function conversion circuit 13, the function conversion circuit 13 is used to connect the state indication pin ACTIVE of the control chip U1 to the state receiving pin RLED of the connector J1, so that the state indication pin ACTIVE is connected to the state of the connector J1 The receiving pin RLED sends out the working state signal of the hard disk, and the function conversion circuit 13 is also used to provide a high-level signal to the interleaved start pin STAGER of the control chip U1, so as to ...

Abstract

A control circuit for a hard disk drive (HDD) includes a control chip, a connector connected between the control chip and a motherboard, and a function transform circuit connected between the control chip and the connector. A status pin of the control chip is connected to a status receiving pin of the connector through the function transform circuit, to send a working state signal of the hard disk drive to the status receiving pin of the connector. The status receiving pin shows a normal operation of the HDD through a light emitting diode connected to the status receiving pin. The function transform circuit provides a high level signal to a staggered spin-up pin of the control chip, to make the control chip control the hard disk drive to execute staggered spin-up function.

Description

technical field [0001] The invention relates to a control circuit, in particular to a hard disk control circuit applied to a hard disk. Background technique [0002] The hard disk usually has two functions, one is the normal working state function (ACTIVE), which is used to display whether the hard disk is in a normal working state, and the other is the staggered startup function (Staggered Spin-up), which is used to realize the hard disk in order power on. However, in the design of the existing hard disk system, usually only the ACTIVE function is designed, and the Staggered Spin-up function is not designed on the system. Therefore, during the use of the hard disk, only the ACTIVE function can be realized instead of the ACTIVE function. The function of Staggered Spin-up. Contents of the invention [0003] The invention provides a hard disk control circuit capable of realizing both the ACTIVE function and the SPIN-UP function. [0004] A hard disk control circuit, compr...
