PCA9450C for IMX8Plus

Hello NXP community,

We are using the PMIC @PCA9450CHNY in our project to power on the MPU #IMX8Plus. We intend to use LDO4 to generate a power rail of 2V5 for other components on the board.

We need clarification on whether this is feasible (given that it's OFF by default). Additionally, if we decide to use it, will the sequence be the same as with the PCA9450AA, or do we need to configure it using the I2C Bus?

Furthermore, will the sequence be generated directly by the 5V SYS power, or does it require the I2C control of the IMX8?

Thanks.
