What is the recommended i.mx258 security PMIC ?

[ronaldbenvenutt]

The datasheet IMX25CEC.pdf revision 10, 07/2013 says the power-up sequence when using dryice. This is not accoplished using the PMIC MC34704 as used on the PDK.

Could be used the PF3000 ?

Hi ronald

I am afraid such pmic is not available.

PF3000 is designed for new i.MX6/7 processors,

also it has not buck/boost 3.3V as MC34704 REG2,5.

Best regards

igor

Hi Igor :

About availability, I bought some units from Digikey, and they are doing well. Will contact Freescale.

I don't need boost regulators, my product only runs from USB, and doesn't contains battery.

Hi,

There is a block "3channel dc-dc or 5 channel LDO"  present in imx28x to support pmic to some extent.

imx28 is different processor from i.MX25.
