Integrated Device Technology, Inc. (IDT) has announced a wireless power receiver meeting the Wireless Power Consortium’s (WPC) 1.1 “Qi” specification and optimized for high-volume portable consumer applications. The new device expands upon IDT’s wireless power family, offering portable device manufacturers a high-efficiency, cost-effective wireless power solution for universal compatibility with the next-generation of Qi chargingbases.
The IDTP9025 is a single-chip wireless power receiver IC certified to meet the requirements of the WPC 1.1 specification, offering improved foreign object detection (FOD) compared to earlier versions of the standard. The highly-integrated device includes an onboard synchronous full-bridge rectifier and low-resistance low-dropout (LDO) regulator, enabling customers to achieve excellent power transfer efficiency with minimal external component count and board space. The high-efficiency, cost-effective design is ideal for use in high-volume portable devices where battery life and physical size are a primary concern, such as in smartphones, tablets, and related accessories.
“Our latest WPC 1.1 wireless power receiver expands our leading wireless power portfolio to address high-volume portable consumer products,” said Arman Naghavi, vice president and general manager of the Analog and Power Division at IDT. “The IDTP9025 enables our customers to develop compact, high-efficiency wireless power solutions compliant to the latest standards, ensuring universal compatibility with any Qi charging base. We also provide a WPC 1.1-certified reference design and layout guidelines with our evaluation kits, making it easy for our customers to obtain WPC certification for their products with minimal effort.”
For added control, IDTP9025 is capable of passing communication and power transfer information to a local microcontroller, as well as fault and safety monitors, through the integrated I2C port. This allows the customer to build custom control algorithms and user interfaces to enhance the user experience. In addition to an evaluation kit with WPC-certified reference design, IDT supports its customers with a design-in guide and powerful support tools to further ease the development process.
The IDTP9025 is currently sampling to qualified customers and is available in a compact 3 x 2.5 mm WLCSP package. The IDTP9025 part number is priced at $2.44 each for volumes of 1,000 units. For more information about IDT’s wireless power ICs, visit www.wirelesspowerbyidt.com.
