Toshiba chipset promises faster wireless charging

In a development set to enable faster wireless charging of mobile devices, Toshiba has announced enhanced versions of its TB6865FG power transmitter and TC7763WBG receiver chipset.

The wireless power chipset now supports 5W power transfer and is compatible with the Qi Standard Low Power Specifications version 1.1. Features include a foreign object detection function and an integrated digital logic controller that reduces component count and minimises design complexity. Target applications include smartphones, game controllers and other portable devices. Built with Toshiba's mixed signal process with optimised mosfet design, the TB6865FG integrates an mcu that can drive four external mosfet H Bridges of four coils for a free positioning architecture supporting two mobile devices. The TC7763WBG receiver combines modulation and control circuitry with a rectifier power pickup, built in LDO and circuit protection functions. The transmitter ic is housed in LQFP-100 14 x 14mm package, while the receiver ic is supplied in a WCSP-28 2.4 x 3.67 x 0.5mm package.
