Extending capability to tablet devices intended to speed wireless power technology adoption

LAS VEGAS, Jan. 6, 2015 — (PRNewswire) —  CONSUMER ELECTRONICS SHOW (CES) – Toshiba America Electronic Components, Inc. ( TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today introduced its newest IC enabling wireless mobile device charging. The TC7765WBG wireless power receiver controller IC effectively manages the 12-watt power transfer necessary for wireless charging of tablet devices. Compatible with the Qi low-power specification version 1.1 defined by the Wireless Power Consortium (WPC), the new IC delivers a user experience comparable to that of conventional wired charging for tablets, as well as smartphones and other portable devices. TAEC will demonstrate the new receiver IC this week at CES 2015 in Las Vegas, Nevada.

ABI Research¹ forecasts that the installed base of mobile devices – tablets, smartphones, wearables, notebooks and basic mobile phones – will reach 8 billion by 2019. This will, in turn, create a huge installed base for rechargeable batteries and charging solutions, including wireless solutions enabled by the Toshiba controller IC portfolio.

"While wireless power technology is growing in popularity, broader adoption has been hindered by the lack of a solution with sufficient power to wirelessly charge tablet devices," said Deepak Mithani, senior director of the Mixed Signal Business Unit, System LSI Group at TAEC. "With this addition to our portfolio of wireless charging ICs, Toshiba is taking an active role in driving the industry to clear this hurdle so that it can keep pace with consumer demand."

The TC7765WBG wireless power receiver controller IC is built with Toshiba's mixed-signal process using a high-performance MOSFET design that maximizes power efficiency and thermal performance. The IC combines modulation and control circuitry with a rectifier power pickup, I²C interface and circuit protection functions. Compliance with the "Foreign Object Detection" (FOD) aspect of the Qi specification prevents heating of any metal objects in the path of wireless power transfer between the receiver and the transmitter.

The 12W receiver IC is designed in the same size package as Toshiba's 5W wireless power receiver controller TC7763WBG – a compact WCSP-28 2.4mm x 3.67mm x 0.5mm package – further facilitating design-in and contributing to the new chipset's backward compatibility with the lower-power receiver IC. Combining the TC7765WBG with a copper coil, charging IC and peripheral components creates a wireless power receiver. Joining the receiver with a Qi-compliant wireless power transmitter containing a Toshiba wireless power transmitter IC (such as TB6865AFG Enhanced version) forms a complete wireless power charging solution.

Availability
Samples of the TC7765WBG wireless power receiver IC will be available at the end of this month, with mass production set to begin in Q2 2015.
