First Qi-Certified MP-A2 15W Transmitter System

September 28, 2016 by Jeff Shepard

Toshiba Corporation's Storage & Electronic Devices Solutions Company today announced that a wireless power transmitter system using its TC7718FTG 15W wireless power transmitter IC, which was introduced earlier this year, has been certified as Qi v1.2 EPP (Extended Power Profile) compliant by the Wireless Power Consortium (WPC). The system adopts MP-A2, which allows a simple system configuration, and is the industry's first Qi-certified MP-A2 transmitter system.

Connected to a microcontroller, TC7718FTG realizes a wireless power transmitter system compliant with Qi standard. Toshiba’s original cutting-edge CD-0.13 process realizes a small package and high efficiency, making system integration easy while securing a small footprint. A 15W wireless transmitter formed with the new IC will recharge devices quickly, at a rate equal to or shorter than wired chargers. The IC is suitable for use in wide range of applications including mobile devices, such as smartphones and tablets, and industrial devices.

A wireless power transmitter system using TC7718FTG is compatible with a 5W receiver system using Toshiba's 5W receiver IC TC7764WBG, and a 10W receiver system using its 10W receiver IC TC7765WBG, both of which are in mass production. In combination with a 15W receiver IC TC7766WBG already certified as the Qi v1.2 EPP compliant, the wireless power system can receive up to 15W.

Toshiba is the industry’s first company to provide Qi v1.2 EPP-certified products for both 15W wireless power transmitters and receivers. Main features include: WPC Qi v1.2 compliant (in combination with a microcontroller); Full-bridge gate driver (also compatible with half-bridge): 1 channel; Built in low—pass filter for recovery of ASK signal; Built in LDO (3.3V output); Operating frequency 110kHz to 205kHz; Packaged in a P-VQFN36-0505-0.40.
