How to connect the power cord and ground wire when charging a lithium battery using a USB-TYPE-C interface? [Copy link]

I use TP4056 to charge a lithium battery. The interface uses a 6-pin USB-TYPE-C female socket. How should I connect the power and ground wires? Which wires do I need to connect?

VBUS is the power supply, and GND is the ground line. You can also define it yourself, but then you have to make the line yourself.

Do I just need to connect VBUS and GND?

Generally, you also need to connect CC1 and CC2 to the ground through a 5K1 resistor so that the host can recognize the device. If it is only powered and the current is small, it may not be connected.

For the chip, pin 4 is the positive input terminal of the input voltage, and pin 3 is the ground terminal.

Pin 5 is the positive pin of the battery

Got it. Thanks.

OK, thanks

You want to ask about the function definition of this pin?
