ROHM's BM92AxxMWV series of power receiving controller ICs support the latest USB Power Delivery (USBPD) protocol with the USB Type-C connector. Compatibility with USB Type-C Rev1.1 and USBPD Rev2.0 makes it possible to supply up to 100W (20V/5A) between USB Type-C devices that up to now was limited to 7.5W. As a result, even devices with larger power requirements such as notebook PCs and TVs can be powered from a USB port. And for conventional USB equipped applications (i.e. smartphones, tablets) faster charging is enabled. In addition, functional optimization and miniaturization are achieved by leveraging advanced micro 0.13um BiCDMOS and high voltage processes along with circuit technology.

BM92AxxMWV Series Features

A max. of 100W can be transmitted through the USB Type-CTM connector. Connected devices automatically enter into a power contract after detecting requirements to supply optimum power between 7.5W (5V/1.5A) and 100W (20V/5A). In addition, bidirectional power supply is possible, with the source and receiver switching sides. And by switching to 27W (9V/3A) supply smaller devices without large power requirements such as smartphone and tablets can be charged up to 4x faster than conventional USB1.2 (5V/1.5A).

DisplayPort Alternate Mode compatibility eliminates the need for separate dedicated video cables.

Support for DisplayPort Alternate Mode is also provided for carrying video signals over USB. The capability to deliver high-speed data, video, and an unprecedented amount of power over a single cable represents a breakthrough achievement that is expected to improve convenience while minimizing clutter and waste.

Configurable using the fewest number of external parts in the industry (a ROHM advantage)

Advanced 0.13um BiCDMOS processes and circuit technology make it possible to eliminate the FET and separate power supply for power receiving operation. This reduces the number of external parts by more than 20 (including the external power supply IC), contributing to greater miniaturization.
