Introduction

This board is dedicated to supplying power with USB Type-C Power Delivery, and the voltage profile (PDO) is 5V, 9V, 12V, 15V, and 20V.
If you want to check the operation of Power Delivery, please prepare a capable of receiving power USB Type-C Power Delivery device and USB Type-C dedicated cable.
Please use selling separately “BM92A12MWV-EVK-001 (20V)”, “BM92A13MWV-EVK-001 (15V)” and “BM92A14MWV-EVK-001 (9V)” for capable of receiving power USB Type-C Power Delivery device.

VEX pin :5V voltage input pin. Although it is named VEX pin on the board, it is connected to the VSVR pin of the PDIC.
VSVR pin :5V or 9V or 12V or 15V or 20V voltage input pin. Although it is named VSVR pin on the board, it is connected to the VEX pin of the PDIC.
CC1, CC2 pin: You can monitor the communication waveform (BMC waveform) with USB Power Delivery.
VBUS pin : It is connected to the VB pin of PDIC and the VBUS pin of the Type-C Receptacle. You can monitor the VBUS voltage to power the Sink side.

How to use and evaluate

Please input 5V to VEX pin and 5V or 9V or 12V or 15V or 20V to the VSVR pin of this board.

Power Delivery Operating Waveform
When connecting this board (Source side) and power receiving device (Sink side) using a Type-C dedicated cable, the Source side detects the Sink side and outputs 5V voltage to the VBUS pin. After outputting 5V voltage on the Source side, it communicates with the Type-C controller IC in the dedicated cable to acquire cable information.
After communicating with the cable on the Source side, the Source side transmits its own power profile information to the Sink side. (Source Capability)
The Sink side requests an appropriate voltage from the power profile to the Source side. (Request)
In response to the Sink side voltage request, if the Source side is able to deal with it, notify the Sink side that it is acknowledged. (Accept)
The Source side outputs the requested voltage to the VBUS pin.
After outputting the required voltage, the Source side notifies the Sink side that the requested voltage has been output. (PS_RDY)
After confirming the requested voltage, the Sink side turns on the FET switch on the VBUS line.
