Can your PCs, Monitors, Docking Stations and Peripherals meet higher power requirements via USB? Can you charge your portable devices such as smartphones and tablets 4x faster through USB port? This is now possible with the new power controller ICs (BM92TxxMWV series) with expanded power levels upto 100W for Type-C connected devices.
Referring to the press release, the latest USB connector and power transmission standards developed by USB-IF are focusing towards all-in-one cable solution to deliver high power, high-speed data, and even 4K video simultaneously over a single USB-cable so as to eliminating the need for multiple dedicated cables, providing greater convenience while reducing clutter and waste.
Combining the new Type-C connector, which boasts of a smaller, reversible, flippable cable design robust enough for laptops but slim enough for mobile phones, with USB PD that offers scalable power using multiple power delivery modes, results in a common, future-proof interface, as stated in the release. Adding further,ROHM leverages leading BiCDMOS processes and circuit technologies to develop USB PD controller ICs optimised for these latest USB standards.
The key features of ROHM power controller ICs are as highlighted below:
- Supports up to 100W of power supply using USB Type-C connectors: With the new USB Power Delivery standard, optimised power delivery (scalable from 7.5W to 100W using multiple power delivery modes) is enabled in both directions between USB Type-C connected systems through a power contract that determines the Provider (Supply) and Consumer (Receiver) devices. This achieves maximum efficiency, since only the required amount of power is requested and only the amount of power available is provided.
- DisplayPort tm Alternate Mode compatibility eliminates the need for separate dedicated video cables: Support for DisplayPort tm 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 minimising clutter and waste.
- Fewer parts required: 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 miniaturisation.
