“Today’s phones are essential for digital living, as well as being a critical business tool for many. Significantly faster charging with our STWLC99 increases their availability and brings extra value to users’ lives,” said Francesco Italia, General Manager, Analog Custom Products Division, STMicroelectronics. “Its unprecedented power also changes the outlook for equipment such as battery-powered industrial tools, medical monitors, medicine pumps, mobile robots, and drones, enabling long runtimes with faster turnaround.”

In addition to enhancing user convenience, high-power wireless charging lets designers create industrial products that are free of power sockets and cords, which can deliver various advantages. Eliminating the charging socket can save space and allow sealing against water or dust ingress in challenging environments. Complications due to twisting or tangling of the cord can be avoided. Independently mobile devices such as robots and drones can recharge easily without a mechanism or human intervention to connect the cable.

Housed in a 4.859m x 4.859mm wafer-level chip-scale package (WLCSP), the STWLC99 is in production now and available from $2.50.
