10 Momentus 5400 FDE.4 SATA Product Manual, Rev. C

2.9.1.1 Typical current profile

Figure 1. Typical +5V only startup and operation current profile

2.9.2 Deferred spinup

Momentus 5400 FDE.4 SATA drives do not support the deferre

d spinup option. If you require this option, refer

to the Momentus 5400.3 SATA Blade Server family of drives.

2.9.3 Conducted noise

Input noise ripple is measured at the host system power

supply across an equivalent 15-ohm resistive load on

the +5 volt line.

Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave

injected noise at up to 10 MHz.

Note. Equ

ivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write

current.

2.9.4 Voltage tolerance

Voltage tolerance (including noise):

± 5%
