IDT Announces World\'s First 30W Wireless Charging Chipset

23 July 2019

SAN JOSE, Calif., July 23, 2019 /PRNewswire/ -- Integrated Device Technology, Inc. (IDT), a wholly owned subsidiary of Renesas Electronics Corporation (TSE: 6723), today announced sampling of the P9415 receiver and P9247 transmitter that work together to enable smartphones to charge wirelessly with up to 30W of power, narrowing the charging time gap between wireless and wired charging options.

IDT's new wireless charging chipset enables smartphones to wirelessly charge as quickly as using wired connections.

"At the IDT lab in San Jose, we have met this historic challenge with these innovative ICs that boast 90% of DC to DC efficiency for 30W of power transfer with a standard low profile coil (< 0.35 mm) suitable for smartphone integration," said Christopher Stephens, vice president and general manager of IDT's Wireless Power Division. "Very fast wireless charging for smartphones has been the holy grail in the industry for the last eight years and the P9415 / P9247 chipset is the latest example of IDT's continued advancement of state-of-the-art wireless charging technology. We expect this release to spur even broader adoption of wireless charging in 4G and 5G smartphones."

The P9415 receiver accommodates up to 20V out of the onboard LDO with the ultra-accurate current sense capability necessary for high power applications. It is footprint compatible with IDT's existing P9382A 15V receiver to provide a compelling upgrade option delivering even faster charging times. Featuring IDT's popular WattshareTM technology with up to 10W of transmit power capability, it can also unlock the ecosystem potential for OEMs to charge smartwatches, ear buds and other devices on the go. Most critically, the device has been designed and tested for robustness in the over-voltage and load transient situations inherent in wireless power transfer at these very high power levels.

The P9247 transmitter delivers up to 30W of power to the receiver and is truly converged, accommodating all Qi-based power transfer protocols (including BPP, EPP, and proprietary protocol extensions), as well as popular wall adapter protocols. The P9247 also incorporates new technology for real-time foreign object detection (FOD), ensuring maximum utility and safety for customers. Additionally, the transmitter allows for power adjustment via frequency, duty-cycle, and/or bridge voltage adjustment and offers significant margin to EMI requirements in all regions of the world.

Both devices are sampling now to qualified customers. Requests for datasheets and samples can be submitted at and
