The PSU is composed of two main blocks:
●
power management integrated circuit (PMIC, NXP PF0100E0 -

● additional generic power management circuitry that completes
PMIC functionalities.
The PSU:
●
generates the proper power-up sequence required by i.MX
processor and surrounding memories and peripherals
● synchronizes the powering up of carrier board in order to
prevent back power
●
provides some spare regulated voltages that can be used to
power carrier board devices
