Looking for a powerbank chip that can use a single USB-C as in and output

For future drivers I am looking for a simple chip solution that combines in and output on just one USB-C socket

basically a embedded solution with one chip architecture some caps and one inductor

This chip has separate In and outputs so not useable für single port

OTG has nothing to do with the single input/output to charge and Power out
OTG simply means you can connect a smartphone and USB stick and they share data

Are you looking for a USB-C 3A controller or a USB-C PD controller?

A bit expensive, but will work well as a DRP port, as well as communicating over I2C:

Its just a router, so this would not buck or boost the voltage charging or discharging battery to USB

What you want to look for is a dual-role port, or DRP as I mentioned before.

Also, sorry for before. I thought you only needed a power passthrough port.
