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.
