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.
