TOSHIBA Makes up for WIRELESS Charging!

Toshiba Electronics Europe has announced a free positioning wireless charging chipset for charging smartphones and other mobiles on a battery charging pad.
The chipset is 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 charging.

The position of a mobile device is detected by the TB6865FG and one of the coils is energised for charging. According to the supplier, this improves efficiency and allows wide product placement on the pad.

A 74% efficiency across a most of the charging area is specified.

The TB6865FG also allows the control of two coils, so two mobile products can be charged simultaneously.


The TB6865FG transmitter integrates both microcontroller and analogue elements including PWM circuitry, switching control, on-board filter and a pre-driver circuit.

The TB6860WBG receiver combines modulation and control circuitry with a rectifier power pickup, built-in DC-DC buck converter and protection functions.
The TB6860WBG offers a programmable charging profile via I2C control. The latter provides an integrated DC-DC converter for high-efficiency, high-current charging with a charge current of up to 1.2A.

Integrated protection for the receiver IC covers input voltage, output current, over-temperature conditions and metal detection.
The TB6865FG is supplied in a LQFP100 14mm x 14mm package while the TB6860WBG is supplied as a WCSP39 4.29mm x 2.69mm device.
