Toshiba Unveils First Single-Chip 15W Wireless Power Receiver IC
Toshiba America Electronic Components, Inc. (TAEC) has announced the industry’s first single-chip wireless power receiver (RX), titled TC7766WBG. The receiver can operate at 15 watts (W) and is compliant with Qi™ v1.2, the wireless charging standard.
According to the manufacturer, the TC7766WBG is designed to triple the received power capability of its predecessors while retaining the same chip size. This extra juice would enable wireless power for subsequent charging of mobile devices at speeds comparable to or, in some cases, faster than conventional wired chargers, Toshiba said in a press statement.
The new 15W chip packs all the functions needed to construct a standalone wireless power transfer RX system. Further, the TC7766WBG is compatible with Toshiba’s TB6865AFG 5W transmitter (TX) IC and its upcoming 15W TX IC.
“The ‘holy grail’ for wireless charging for high-performance portable devices has been 15W, and we’ve been steadily working toward this objective with continued additions to our family of wireless charging devices,” said Deepak Mithani, senior director of the Mixed Signal Business Unit, System LSI Group at TAEC. “Making a 15W wireless power chip that allows for rapid charging available to our customers in a package with the same footprint as our previous product will help speed the design-in process and help them get advanced charging devices to market more quickly.”
The RX receiver handles a maximum output current of 1.7 amps (A) and output voltage range of 5 volts (V) to 14V. It features full protections, as well as the new Qi Foreign Object Detection functions. The product is housed in a low-Z-height WCSP28 package, which measures 2.4mm x 3.67mm x 0.5mm.
Samples of the TC7766WBG wireless power receiver IC will be available by the end of 2015, and mass production will begin in spring 2016.
