ROHM has received certification from WPC (Wireless Power Consortium) for its reference design using the BD57020MWV wireless power transmitter IC. This is the first device in the world certified to be compliant with the new Qi medium power specification.
WPC’s Qi standard for medium power has attracted attention as a next-generation standard for inductive power transmission that will enable wireless charging of tablet PCs while allowing smartphones and other mobile devices to be charged up to 3x faster than the existing low-power standard (5W). In addition, a Foreign Object Detection (FOD) function is included to provide greater safety by detecting foreign metallic objects before power transfer to protect against possible damage due to overheating.
ROHM also developed a reference design that will help accelerate adoption in applications that will benefit from wireless charging.
