In recent years, the demand for reducing commercial waste has grown in Europe. Among other things, universal, worldwide applicable chargers and connectors for electronic devices are to be developed and applied. Accordingly, the interest in the USB Type C connector developed by the USB Implementers Forum and the USB Power Delivery standard is a trendsetting interface with a compact plug-in connector that, in contrast to earlier USB connectors, is not sensitive to its orientation when plugged.

USB Power Delivery is a USB Power Expansion Standard for delivering up to 100W via USB. This enables the power supply of larger devices, such as laptops, which could not be supplied with the conventional USB technology. At the same time, the loading times of portable devices are considerably reduced. According to the USBPD protocol, the connected devices handle the power requirements among themselves in order to determine the optimum values for voltage and current.

The USBPD communication requires a new, special CC cable, which works independently of the conventional USB data transmission.

Thus, USBPD expands the conventional USB-transferable power of 15W with USB Type-C compliant devices up to 100W (20V, 5A), so that even larger devices such as laptops or TVs can be powered by USB. At the same time, a contribution is being made to the transformation of the infrastructure, while the number of USB ports in private households and hotels continues to grow.

The new BM92AxxMWV-EVK-01 series is based on the USBPD controller IC from Rohm, which supports the USB standards Type-C Rev1.1 and USBPD Rev2.0 for connection to USB Type C devices. In order to achieve optimal performance and functionality, Rohm uses advanced BiCDMOS processes and circuit technology to develop the USBPD controller ICs. In a first step, six boards in transmitter and receiver design are presented which are adapted to the requirements of a wide range of applications. The transmitter and receiver boards can be combined by the user in order to easily implement and evaluate the USBPD functionality.

The boards are now available through the online distributors Chip One Stop, Zaiko Store (Core Staff) and RS Components. The supplementary documentation is available for download on the Rohm website.
