Where can I find the IMX8QuadMax core voltages and corresponding currents?

[ashan]

Hi All,

We are going to design our own custom board using IMX8QM SoC. But we could not find any core voltages and corresponding currents regarding this processor. Could you please let me know how to find them?

And also do we have to use PF8100 or PF8200 PMIC chips to give those voltages? Can't we use different chip (without I2C) instead of that? Using PF8200 seems really complex with I2C controlling for power requirements. In IMX6Q there was no such PMIC recommendations like in IMX8QM.

Thanks

for voltage and current, you can refer to the data sheet as below:

for imx8QM, we recommends PF8100 or PF8200, current board uses PF8100 , one can refer to the schematic as below：
