Momentus 5400.5 SATA Product Manual, Rev. B
2.9.1.1 Typical current profile
Figure 1. Typical +5V only startup and operation current profile
2.9.2 Deferred spinup
Momentus 5400.5 SAT A drives do no t suppor t the def erre d spi nup option. If you requir e this opti on , 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. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.
2.9.4 Voltage tolerance
Voltage tolerance (including noise):
5V ± 5%
