MX8QM recommended PMIC

diarmuidcollins — Fri, 18 Jul 2025 14:52:10 GMT

I am planning a design based on the MX8QM processor. We will be using the following interfaces

A72 2x cores
PCIe interface
eMMC interface
Ethernet interface

We will not use the GPU, VPU, display etc.

On the PMIC selection page, https://www.nxp.com/products/power-management/pmics-and-sbcs:POWR_MAN_USER_INTERFACE the device recommended is PF81-PF82 which according to the product page is Not Recommended.

So what is the recommended device?

Could we use PCA9450C ?

Regards

Hello,

Unfortunately, there are no replacement part numbers for PF81-PF82 from NXP.

I suggest you look for third-party solutions as:

Integrated Power Supply Design for NXP i.MX8 QuadMax Processor

Also, PCA9450 PMIC is not compatible for i.MX8QM since power requirements are higher current power consumption and different power-up/power-off sequences compared to i.MX8MN/M/P processors.

Keep in mind that PF81-PF82 product family is part of our Longevity program until May 2034

Best regards.
