Power Control (CM-i.MX27)

Power Control is handled by the MC13783 power management IC (PMIC).

Input voltage

Connect any voltage between 6V and 12V DC to the power plug of the DEV-i.MX27/35 board.

Power up/down

Power up

The core modules is automatically powered up if the input voltage is supplied.

If the board is in power off mode (e.g., after a shutdown in Linux), hit button PON on the DEV board to power up the board.

Power down

Shutting down Linux powers sets the PMIC in User Off mode, i.e., all PMIC voltages and the processor are powered off after shutdown is complete.

We measured a power consumption of about 0.5 Watts in this mode.
