STUSB4500 Default PDOs without I2C

OlafM

Hi, 

We like to use the STUSB4500 without having it to progamm via the I2C. So we need to use the standard configuration. If I understand well, these are has 3 PDOs: 5v/1.5A - 15V/1.5A and 20V/1A.

However, the 20V/1A is too high. Is there a way to prevent the 20V/1A. and to only have the two PDOs  5v/1.5A - 15V/1.5A active. (without to programm the I2C)

Thanks,

Olaf

Hi,

Indeed the 5V, 9V and 12 V output would be great. Looking at the table, I see SNK_PDO_Numb =3 and Power_only_Above5V =0. However, I do not understand, how and which pins I need to use to configure? Can you explain?

Thanks
