5.1.6 Hot Plug

The disk drive is "Hot Plug Capable" which is based on Serial ATA Revision 2.5.

It is recommended to use the pre-charge resistor for protection from over current at +5V power supply circuit in the host system when the disk drive is hot- plugged.

(Refer to the Serial ATA Revision 2.5.)

The equivalent circuit of +5V power supply at Hot Plugging is in the following figure.

It is necessary to choose pre-charge resistor RL value, which is in permissible range of +5V power supply specification at the host system.

Refer to the equivalent circuit when the optimized value of pre-charge resistor RL. It is recommended to choose the minimum value which is in permissible range of +5V power supply specification at the host system. Because it is possible that rush current occurs again when P8, P9 pin connection after P7 (+5V pre-charge pin) connection dependent on the insertion speed.
