i just use HD3SS3220 as Device mode,
we want to use two types of charging,(1.type C 2. 12V DC source).
Because we are worried that TYPE-C's power is not enough.
1. now my problem is that 12V DC source to 5V, and this 5V how to provide to HD3SS3220 and how to connect?
2. The MCU integrates USB A,and I use HD3SS3220 which turn usb A to type-c, and HD3SS3220 's I2C PIN should i connect it?
3. HD3SS3220 's the 23rd PIN INT_N/OUT3, the 25th PIN SDA/OUT1 , the 26th PIN SCL/OUT2 . What do they do? What are their functions?
Thanks in advance for your answer.
