Las Vegas, Nev. — At the 2014 Consumer Electronics Show (CES), Toshiba America Electronic Components, Inc. (TAEC) unveiled new enhancements to its TB6865FG power transmitter and TC7763WBG receiver chipset that enable wireless power transfer to charge mobile devices faster. The wireless power chipset now supports 5-watt power transfer, and is compatible with the Qi low-power specifications version 1.1 defined by the Wireless Power Consortium (WPC), including rigorous Foreign Object Detection (FOD). The chipset also integrates digital controller logic that reduces component count and minimizes design complexity, said TAEC.
“We are seeing a strong interest in wireless power technology for products like smartphones, game controllers, and other portable devices,” says Deepak Mithani, senior director of the Mixed Signal Business Unit, System LSI Group at TAEC, in a statement. “Besides the advantage of charging a device without the use of a cable, one interesting and emerging application is for mobile waterproof gadgets where a device is fully enclosed in its housing with no exposed connectors. Customers are demanding a quick way to charge their portable electronics and this chipset provides a convenient and effective way to satisfy their demand.”
The wireless power chipset is built with the company’s mixed-signal process with optimized MOSFET design that delivers high-performance, allowing mobile device placement on the battery charging pad. The TB6865FG integrates an MCU and can drive four external MOSFET H Bridges of four 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 linear dropout regulator (LDO) and circuit protection functions.
The transmitter IC is housed in a LQFP-100 14- x14-mm package and the receiver IC is supplied in a compact WCSP-28 2.4- x 3.67- x 0.5-mm package.
Availability: The TB6865FG and TB7763WBG chipset is currently sampling.
Pricing: One piece sample price of the TB6865FG power transmitter is $7.00 and the TB7763WBG receiver is priced at $3.50.
