4.2
The system design must comply with power-up sequence, power-down sequence and steady state
guidelines as described in this section to guarantee the 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.MX53xA processor (worst-case scenario)
• The consequent steps in power up sequence should not start before the previous step supplies
shows the USB interface current consumption.
Power Supplies Requirements and Restrictions
have been stabilized within 90-110% of their nominal voltage, unless stated otherwise.
