Wireless charging integrated in pen solutions
Summary
The Renesas single-chip wireless power receiver IC delivers small size and high efficiency compared to alternative high-frequency charging solutions. This novel and innovative concept brings the convenience of wireless charging to accessories, enabling users to creatively express themselves on both smartphones and tablets. “Renesas is proud to expand our work with a proven leader such as Wacom to help bring leading-edge wireless charging solutions to the digital pen market,” said Amit Bavisi, Vice President and general manager of Renesas’ Wireless Power Group, Mobility Infrastructure and IoT Power Business Division. A unique ping-detect feature gives an early indication of the wireless charger connection and improves thermal performance at the end of complete battery charging. Additionally, the integrated 32-bit processor offers a high level of programmability and design parameters that can be easily configured to work with small rod coils that fit into digital pens.
