Wireless Charging Technology

Wireless charging technology is becoming increasingly popular in the mobile device sector by eliminating power cords, providing the ability to send power and even data across multiple interfaces. In addition, wireless charging is expected to increase convenience and decrease waste by allowing multiple devices to use a single charger. Removing cords and connectors translates to improved safety, size, and reliability - as well as a better user experience. Standards organizations such as Wireless Power Consortium (WPC) and Air Fuel exist to develop and promote international standards for wireless charging that are gradually being introduced in the smartphone and infrastructure markets in the US and Europe. As a regular member of WPC, ROHM actively participates from the development stage of WPC's increasingly popular Qi standard and has been quick to develop products that meet market needs. ROHM leads the industry in product development, including reference designs with integrated wireless charge control IC that have already obtained Qi certification. ROHM offers a broad portfolio of wireless charging products for wireless power solutions.
