2.8.1.1 Typical current profiles
Figure 1. Typical 12V startup and operation current profile
2.8.2 Conducted noise
Input noise ripple is measured at the host system power
supply across an equivalent 80-ohm resistive load on
the 12V line or an equivalent 15-ohm resistive load on the 5V line.
• Using 12V power, the drive is expected to operate with
a maximum of 120mV peak-to-peak square-wave
injected noise at up to 10MHz.
• Using 5V power, the drive is expected to operate with a maximum of 1
00mV peak-to-peak square-wave
injected noise at up to 10MHz.
Note. Equ
ivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.
2.8.3 Voltage tolerance
Voltage tolerance (including noise):
•5V ± 5%
• 12V ± 10%
