We are making customized boards using i.MX8MQ.
In the process of purchasing a part, the MC34PF4210A1ES is out of stock and we are looking for a replacement part.
Can you suggest a replacement for PMIC for I.MX8MQ?
In this case I would recommend you to use the MMPF0100NPAES PMIC as a replacement for the MC34PF4210A1ES. MMPF0100 family is pin-to-pin compatible with the PF4210 family.
Just take in mind that for the MMPF0100 PMIC, there is no OTP pre-programed option with the same configuration as the MC34PF4210A1ES, reason of why I recommended the no-programmed option of the MMPF0100, but you can load the MC34PF4210A1ES OTP configuration (attached) into this un-programmed PMIC.
Information about how to do this programming can be found in the following link: https://www.nxp.com/docs/en/application-note/AN4536.pdf
I can recommend you the MMPF0100NPAEP or the MMPF0100NPAZES, however, I think these are also out of stock caused by the global semiconductor shortage.
My recommendation is to contact your local NXP Authorized Distributor from the following page and check directly with them the availability and lead times in you zone.
Even some distributors can program the un-programmed parts for a cost.
If you are currently not working with an NXP Authorized Distributor, I recommend you to contact them directly for details: http://www.nxp.com/support/sample-buy/distributor-network:DISTRIBUTORS
