Hi PMIC expert,

Can i use the GPIO4 and GPIO5 as ADC inputs.

Are both the inputs fail-safe

I see GPIO5 mentioned as fail-safe in the TPS65224 data sheet

Hi Sreenivasa,

only GPIO5 and 6 are fail-safe pins. Both GPIO4 and 5 can be used as ADC in but not at the same time. If they are configured as ADC_IN at the same time only GPIO4 acts like ADC_IN as it has the higher priority in this regard.

regards,

Niko
