Introduction
This board is dedicated to receiving power with USB Type-C Power Delivery.
BM92A12MWV-EVK-001 requests a voltage of 20V, BM92A13MWV-EVK-001 requests a
voltage of 20V, and BM92A14MWV-EVK-001 requests a voltage of 9V.
If you want to check the operation of Power Delivery, please prepare power supply capable
USB Type-C Power Delivery device and USB Type-C dedicated cable.
Please use selling separately “BM92A21MWV-EVK-001” for power supply capable USB
Type-C Power Delivery device.

・VBUS pin：VBUS voltage input pin.You can monitor the VBUS voltage supplied from the
Source side.
・CC1,CC2 pin：You can monitor the communication waveform (BMC waveform) with USB
Power Delivery.
・tChg pin：The pin at the end of the FET on the VBUS Line. In an actual system, a current
load will be drawn from this pin.

How to use and evaluate
1. This board is compatible with Dead Battery, so it can be operated without power supply.
As shown in the picture below, you can check the Power Delivery operation by simply
connecting a USB Power Delivery device capable of supplying power with this board
with Type-C dedicated cable.

Power Delivery Operating Waveform
When connecting this board (Sink side) and power supply device (Source side) using
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, notifies
the Sink side that it 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.
