2.9.1.1Typical current profile

Figure 1. Typical 5V startup and operating current profile

2.9.2Conducted 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 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.

2.9.3Voltage tolerance

Voltage tolerance (including noise):

5V ± 5%
