Wireless charger IC from IDT compatible with both WPC and PMA

Integrated Device Technology has announced dual-mode wireless power receiver IC compatible with both the Wireless Power Consortium (WPC) and Power Matters Alliance (PMA) standards. IDTP9021 complies with the PMA Type 1 Interoperability Specification in addition to the WPC “Qi” standard.

“IDT’s receiver empowers OEMs to easily support multiple standards with a single solution, which is a win-win for both OEMs and consumers,” said Arman Naghavi, vice president and general manager of the Analog and Power Division at IDT. “Since the introduction of the IDTP9020 receiver and IDTP9030 transmitter, IDT has consistently led the competition by equipping its customers with the most advanced wireless power ICs. The IDTP9021 is the latest addition to our growing portfolio, and we’re pleased to be the first device to achieve PMA pre-certification. Future devices will build upon the successes of these products to offer compliance to the latest revisions of the standards along with new features and packaging."

“The Power Matters Alliance seeks to establish the guidelines and standardize an infrastructure for the future of wireless power,” said Ron Resnick, President of Power Matters Alliance. “Companies like IDT are accelerating the progress toward that future with the ability to integrate features and functionality into a monolithic solution that complies with the PMA standard. We’re excited to pre-certify IDT’s IDTP9021 wireless power receiver IC, as it provides OEMs with the necessary components to ensure compatibility with the PMA standard in next generation mobile devices.”

The IDTP9021 integrates a high-efficiency synchronous full bridge rectifier, high-efficiency synchronous buck converter, and control circuits to wirelessly receive an AC power signal from a compatible transmitter and convert it into a regulated 5 V output voltage for powering and charging portal electronics. It automatically switches between WPC and PMA protocols and negotiates the power exchange without user supervision. This simplifies the system architecture and ensures seamless operation during everyday use. The device delivers 5W in WPC and PMA modes in accordance with those standards. When paired with IDT wireless power transmitters, systems can make use of the proprietary power control loop embedded in the communication protocol to achieve a 50% increase in output power to 7.5W.

Pricing and Availability: The IDTP9021 is currently sampling to qualified customers and is available in a 56-lead WLCSP package. The IDTP9021 is priced at $4.32 each for volumes of 1,000 units. For more information about the IDP9021 visit www.wirelesspowerbyidt.com.
