5.1 Physical Interface
5.1.6 Hot Plug
The disk drive is “Hot Plug Capable” which is based on Serial ATA II Extension
to Serial ATA 1.0a Specification.
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 II Extension to Serial ATA 1.0a Specification.)
The equivalent circuit of +5V power supply at Hot Plugging is in the following
figure.
It is necessary to choose pre-charge resistor R
L
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 R
L
.
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.
