Table 17 shows the USB PHY current consumption.

4.2

Supply Power-Up/Power-Down Requirements and Restrictions

The system design must comply with the power-up and power-down sequence guidelines as described in

this section to guarantee reliable operation of the device. Any deviation from these sequences may result

in the following situations:

•

Excessive current during power-up phase

•

Prevention of the device from booting

•

Irreversible damage to the i.MX51 processor (worst-case scenario)
