How do I select different output voltages from the STUSB4500 without using a microcontroller?

[Oktopus15]

I want to use a STUSB4500LBJR for USB-C power delivery. On the datasheet stands that connecting the I2C lines is optional and in another datasheed of the STUSB4500 stands that I don't have to use a microcontroller. But I cannot find information about choosing a voltage output I want from the STUSB4500 on the internet.

Hello Oktopus15,

take care that STUSB4500LBJR is Type-C only for 5V, up to 3A applications.

STUSB4500BJR is USB-C + PD capable (up to 20V, 5A):

 

If you need to change STUSB4500 power profiles, 2 options:

1°) customize once the Non Volatile Memory (check this software package: STSW-STUSB004)

2°) or do it on the fly from your application MCU: STSW-STUSB003

Rgds,
