AI Technical Summary
In existing technologies, the discharge of the capacitor at the front end of the hard drive connector can cause voltage overshoot when the hard drive is connected, which can easily lead to irreversible damage to the hard drive.
Design a hard drive protection circuit, including a switch branch, a voltage comparison module, a capacitor module, and a control module. The control module controls the switching branch to open and close according to the connection status of the hard drive. Combined with the voltage comparison module and the LED module, it ensures that the capacitor module discharges charge in time after the hard drive loses power, thus avoiding overvoltage.
It effectively avoids damage to the hard drive caused by overvoltage due to capacitor module discharge when the hard drive is powered on, ensuring the reliability of the hard drive's working performance, and provides visual prompts for safe insertion time.
