True Single-chip Wireless Power Transmitter and Highest-output-power Single-chip Receiver Solution

Integrated Device Technology, Inc. (IDT) announced the world's first true single-chip wireless power transmitter accompanied by the industry's highest-output-power single-chip receiver solution. IDT's highly integrated multi-mode transmitter reduces board footprint by 80 percent and solution bill-of-materials (BOM) cost by 50 percent compared to existing solutions. The complementary multi-mode receiver outputs twice the power of commonly used solutions, cutting charging time in half.

The IDTP9030 and IDTP9020 comprise a wireless power transmitter and receiver solution designed to meet the Wireless Power Consortium (WPC) Qi standard, which ensures interoperability with any other device meeting the WPC Qi standard. Both transmitter and receiver are capable of "multi-mode" operation, supporting both the Qi standard as well as proprietary formats for added features, improved safety, and increased power output capability. Built-in protocol detection enables dynamic switching between Qi and proprietary modes, creating seamless transitions and a trouble-free user experience. These devices can be used in a myriad of mobile applications for convenient and effortless battery charging.

The IDTP9030 is the most highly integrated wireless power transmitter available today. It combines the features and functionality of dozens of discrete components into a simplified, cost-effective, and highly efficient solution. The integration drastically minimizes the application footprint and component count, enabling customers to design and deploy more compact, cost-efficient, and conveniently located wireless charging stations. These charging stations may be deployed virtually anywhere, including homes, offices, libraries, stores, public waiting areas, automobiles, airports, and airplane seats.

The IDTP9020 is a high-efficiency single-chip wireless power receiver. In Qi mode, the device delivers up to 5 watts to the system. When used with the IDTP9030 transmitter in a proprietary configuration, it can deliver up to 7.5 watts, making the device suitable for powerful mobile devices, such as tablets, smart phones, digitals cameras, GPS units, and headsets. When used in tandem, the IDTP9030 and IDTP9020 become the industry's most efficient end-to-end wireless power solution, resulting in reduced energy costs and faster charging time.

The IDTP9020 and IDTP9030 also feature proprietary multi-layered foreign object detection (FOD), utilizing sophisticated multi-parameter algorithms to assure a high level of safety while avoiding FOD false alarms. Coupled with over-temperature, over-voltage, and over-current protection, IDT's solution offers the most comprehensive suite of protection features on the market, ensuring safe and reliable operation. In addition, the receiver includes support for charging the battery via USB cable when a wireless charging station is not available, eliminating the need for external USB adaptor switches in mobile devices.

The IDTP9030 and IDTP9020 are currently sampling to qualified customers. They are available in 48-lead 6 x 6 mm VFQFN (IDTP9030) and 56-lead 7 x 7 mm TQFN (IDTP9020) packages. The IDTP9030 and IDTP9020 are priced at $4.70 and $3.60 each for volumes of 10,000 units, respectively. For more information, visit www.idt.com/go/wirelesspower.
