Toshiba launches wireless power receiver IC compliant with Qi v1.2

Toshiba America Electronic Components, Inc. (TAEC) said it has introduced a single-chip wireless power receiver (RX) that can operate at 15 watts (W) and is compliant with Qiâ„¢ v1.2, the wireless charging standard.

The TC7766WBG triples the received power capability of its predecessors[2] with advanced design methodologies and the same ultra-compact package footprint. This enables wireless power for subsequent charging of smartphones, tablets and handheld devices at speeds comparable to or, in some cases, faster than conventional wired chargers.

The new 15W chip includes all the functions needed, including rectifier circuits and controllers, to construct a standalone wireless power transfer RX system. Toshiba´s original CD-0.13 process, based on 0.13-micron CMOS/DMOS semiconductor process technology, combines small packaging with high efficiency, facilitating system integration and allowing for a small-footprint, cost-optimized receiver system. The TC7766WBG is compatible with Toshiba´s TB6865AFG[3] 5W transmitter (TX) IC and its upcoming 15W TX IC[4] that also complies with Qi v1.2.

In addition to its 15W maximum output power, the TC7766WBG features maximum output current of 1.7 amps (A) and output voltage range of 5 volts (V) to 14V, full protections, and the new Qi Foreign Object Detection functions. It is housed in a low-Z-height WCSP28 package (2.4mm x 3.67mm x 0.5mm).

Toshiba America Electronic Components, Inc. is an independent operating company owned by Toshiba America, Inc., a subsidiary of Toshiba Corporation. Founded in Tokyo in 1875, Toshiba is at the heart of a global network of over 590 consolidated companies employing over 200,000 people worldwide.
