Wireless charging of mobile devices now as fast as charging by cable

SAN JOSE, Calif., Aug. 17, 2015 — (PRNewswire) —   Toshiba America Electronic Components, Inc. ( TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced it has launched a new wireless power receiver IC that will enable mobile devices to be charged wirelessly as fast as if they were connected to the charger via a cable. The new TC7764WBG is compliant with Qi™ V.1.1.2, the wireless low power charging standard defined by the Wireless Power Consortium (WPC), which includes a dedicated specification for smartphones and mobile accessories.

Wireless charging allows adoption of a fully insulated case free of exposed charging ports, an advantage that is stimulating demand for waterproof and dustproof smartphones and other mobile devices. However, wireless charging has not always been as fast as charging by cable. Toshiba has addressed this problem by optimizing the circuit design of the TC7764WBG compared to its predecessor products, enabling maximum output power of 5W and maximum power conversion efficiency of 95 percent¹. This will allow wireless charger makers utilizing the new IC to achieve performance as fast as that offered by cabled chargers, with added benefits.

"Once the de facto standard for charging mobile devices, cabled chargers will be gradually displaced by wireless power, which is a disruptive and effective technology for device charging today," said Deepak Mithani, senior director of the Mixed Signal Business Unit, System LSI Group at TAEC. "As we continue to expand and improve our offering of wireless power ICs, Toshiba is helping to drive broader consumer adoption and use of cable-free charging technology."

To ensure mobile device safety, the new IC integrates a protocol authentication circuit for power transfers, foreign object detection functions, under-voltage lockout (UVLO) and over voltage detection (OVLO) functions, as well as thermal shutdown function (TSD). The IC is housed in a WCSP28 package measuring just 2.4mm by 3.67mm by 0.5mm.
