This design uses the FUSB302B (C132291) controller + INA226 (C49851) current detection chip to implement the USB-PD protocol. It can be used for DIY wire detectors, charger output capability detectors, etc. It requires an external microcontroller to communicate with the IIC bus. The output voltage and current of USBC, but the chip is more expensive, you can not solder

Jumper function:

H1 jumper: current can be detected here when INA226 is not soldered

H2, H3 jumper: used to connect the USB signal cable of Type-C port to QC3.0 decoy circuit or MicroUSB, and connect according to the instructions on the PCB

H4 jumper: connect according to the instructions on the PCB, supply the 5V voltage of microUSB to the board, or you can supply power externally here

H5 jumper: Connect 3.3V or 5V to VCONN. If you don't understand TypeC principle, don't connect this jumper!

FUSB302B introduction: ON Semiconductor programmable USB Type-C controller with power supply PD (default SNK) USB Type-C port controller

FUSB302B is intended for system designers who want to implement DRP / SRC / SNK USB Type-C connectors but require a small amount of programming. FUSB302B supports USB Type-C detection, including connection and orientation. The FUSB302B integrates the physical layer of the USB BMC power delivery protocol, allowing up to 100 W of power and role interchange. The PD module of BMC fully supports the replacement interface of Type-C specification.
