Toshiba America Electronic Components today announced its free positioning wireless charging chipset consisting of a high-efficiency power transmitter and receiver for charging smartphones and other mobile products anywhere on the battery charging pad. The Toshiba chipset is fully compliant with the Wireless Power Consortium (WPC) Qi interface specification, A4, A8, A12 and A14. It includes the TB6865FG power transmitter and TB6860WBG receiver and features a two-coil control architecture for cost-effective battery charging. The position of a mobile device is detected by the TB6865FG and only one of the coils is energized for charging, thereby preserving efficiency and allowing product freedom of placement. As a result, end users can place a Qi-capable mobile product on a Qi-compliant charging surface and achieve up to 74 percent efficiency across a majority1 of the charging area. In addition, the design flexibility of the TB6865FG allows the control of two coils, so two mobile products can be charged simultaneously.
