2.8.1.1Typical current profiles

Figure 1. Typical 5V startup and operation current profile

2.8.2Conducted 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 250 mV peak-to-peak sine-wave injected noise at a frequency from 100Hz up to 20 MHz.

Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

2.8.3Voltage tolerance

Voltage tolerance (including noise):

5V ±5%
