Type-C charging and OTG chip - LDR6028A

With the popularity of the type-c interface, more and more electronic products now use the type-c interface. So, what is the difference between the type-c interface and the ordinary interface?

Compared with traditional interfaces, type-c mainly has the following highlights

1. It lies in a slimmer design, faster transmission speed (up to 10Gbps) and more powerful power transmission (up to 100W).

2. The biggest feature of the Type-C double-sided pluggable interface is that it supports double-sided insertion of the USB interface, which officially solves the worldwide problem of "USB can never be inserted correctly".

3. At the same time, the USB data cable used with it must also be thinner and lighter.

So is there a suitable chip for the Type-C interface that can charge OTG while charging?
