This manual introduces the characteristics and usage methods of the BM92A15MWV-EVK-001 evaluation board, which can be used to receive power with USB Type-C Power Delivery and request the maximum voltage from the voltage profile (PDO) that the power supply side has.
The ROHM BM92A15MWV-EVK-001 is an evaluation board designed for receiving power via USB Type-C Power Delivery. It requests the maximum voltage available from the voltage profile (PDO) provided by the power supply side. To operate the board, a USB Type-C Power Delivery device and a dedicated cable are required; the manual recommends using the separately sold BM92A21MWV-EVK-001 as the power supply source.
The board features a Type-C receptacle with VBUS, CC1, CC2, and To_Charger pins for monitoring voltage, communication waveforms, and connecting loads. The manual details the Power Delivery operating waveform, explaining the negotiation process where the source detects the sink, communicates cable information, and outputs the requested voltage after a handshake involving Capability, Request, Accept, and PS_RDY signals.
This board is dedicated to receiving power with USB Type-C Power Delivery and requests the maximum voltage from the voltage profile.
The manual recommends using the separately sold BM92A21MWV-EVK-001 as the power supply capable USB Type-C Power Delivery device.
Yes, the board is compatible with Dead Battery and can be operated without a power supply by simply connecting a USB Power Delivery device.
