IDT Introduces Industry’s First WPC 1.1 and PMA 1.1 Dual-mode Wireless Power Receiver

IDT’s Single-chip Wireless Power IC Offers Mobile OEMs Seamless Compatibility Between the Latest Versions of Two Popular Magnetic Induction Wireless Charging Standards

SAN JOSE, Calif., February 24, 2013 – Integrated Device Technology, Inc. (IDT) today announced the industry’s first dual-mode wireless power receiver compatible with both the Wireless Power Consortium’s (WPC) 1.1 Qi standard, as well as the Power Matter’s Alliance (PMA) 1.1 standard. The innovative solution enables OEMs to use a single wireless power receiver IC to develop mobile devices fully compatible with the latest versions of both Qi and PMA charging bases.

The IDTP9023 is a WPC 1.1- and PMA 1.1-compliant single-chip wireless power receiver consisting of a synchronous full-bridge rectifier, high-efficiency synchronous buck converter, and embedded microcontroller used to optimize power delivery to the mobile device’s load, while minimizing application footprint, component count, and thermal dissipation. The new wireless power receiver supports all WPC and PMA receiver coils, as well as proprietary and PCB-based coils for maximum versatility in a wide range of applications, including smart phones, tablets, sleeves, and other accessories.

“We are proud to continue our wireless power technology leadership by announcing the industry’s first single-chip WPC 1.1 and PMA 1.1 dual-mode wireless power receiver solution,” said Arman Naghavi, vice president and general manager of the Analog and Power Division at IDT. “Following the industry’s first dual-mode solution IDT announced last year, our new device gives customers a clear upgrade path to meet the latest magnetic induction standards requirements and offer consumers full compatibility with any Qi- or PMA-certified charging base currently on the market. The chip’s high-efficiency and small application footprint make it well-suited for tomorrow’s ultra-thin, lightweight, and compact portable devices and accessories.”

The embedded microcontroller provides a variety of control features and status indicators beyond the Qi and PMA specifications, enabling the development of sophisticated power delivery schemes and innovative user interfaces. Enhanced communication with IDT’s wireless power transmitters is achieved via a proprietary transmitter/receiver back-channel communication protocol, while an integrated I2C interface provides access to charging status and proprietary alignment guide information.

In addition, flexible firmware and microcontroller programmability enables tuning the coil drive circuitry to maximize power transfer efficiency for various applications and usage scenarios. With excellent power efficiency and compliance to the latest WPC and PMA standards, the device offers a quick battery charge with any Qi- or PMA-compatible charging base. For applications not requiring dual-mode capability, a Qi-only version is available as the IDTP9022.
