Hi Sir,
I am reviewing the application schematic of the STUSB1600 in a dual-role Type-C design. I understand that when STUSB1600 operates as a Source, the output current can be configured through the CC_CAPABILITY_CTRL register.
However, I did not see an explicit current limiting component in the provided schematic. I would like to ask whether ST has any recommended external circuit solutions to further enforce current limitation, such as a preferred power switch or current limiting IC that is compatible with this setup.
Additionally, I would like to confirm: if we only configure the CC_CAPABILITY_CTRL register without any external current limiting components, would the actual output current still exceed the configured 1.5A limit in certain conditions? If so, could you provide a reference circuit diagram or recommendations for suitable current limiting components that ensure proper current regulation?
