4.1.6
USB-OH-1 (OTG + 1 Host Port) Current Consumption
Table 16 shows the USB interface 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 can result in
the following situations:
•
Excessive current during power-up phase
•
Prevention of the device from booting
•
Irreversible damage to the i.MX50 processor (worst-case scenario)
