Wacom pen uses Renesas wireless power


Wireless power charging technology integrated in Wacom Active ES Pen solutions

Renesas Electronics has announced that its wireless power charging technology is integrated in the Active ES pen solutions from Wacom, a maker of digital pen and ink solutions.

“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, VP and general manager of Renesas’ Wireless Power Group, Mobility Infrastructure and IoT Power Business Division. “We continue to be the innovation leader in wireless charging, working with customers around the world to bring the convenience of wireless charging to a variety of platforms.”

“Our customers are always looking for streamlined solutions for charging their digital pens, and Renesas provided us with the much-needed support to deliver a premier solution for our consumers with the small size and power efficiency we needed,” said Sayatake Komine, EVP and head of Wacom’s Technology Solution Business Unit.

Renesas says it swireless power receivers are the world’s highest power density devices and feature high levels of integration and high efficiency at light loads. They are well-suited for low-power applications such as earbud case charging and digital pens. 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, an 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.
