Enabling faster wireless charging of mobile devices, the enhanced TB6865FG power transmitter and TC7763WBG receiver chipset from Toshiba Electronics Europe as been made available. Supporting 5W power transfer and compatible with the QI standard 1.1, the chipset also features a rigorous Foreign Object Detection function and an integrated digital logic controller that reduces component count and minimizes design complexity.

 

 

The TB6865FG integrates an MCU that can drive 4 external MOSFET H Bridges of 4 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 14x14mm package and the receiver IC is supplied in a compact WCSP-28 2.4mm x 3.67mm x 0.5mm package.

The chipset is designed to meet the growing demand for fast and efficient wireless charging of smartphones, game controllers and portable devices. One emerging application for wireless charging is for waterproof mobile gadgets where a device is fully enclosed in its housing with no exposed connections.

The recently announced TC7761WBG IC has been awarded Qi certification for an output power of 3.5 Watt.
