Integrated Device Technology Inc. (IDT) has unveiled a wireless power receiver meeting the Wireless Power Consortium's (WPC) 1.1 Qi specification and optimised for high-volume portable consumer applications. According to the company, the device affords portable device manufacturers a high-efficiency, cost-effective wireless power solution for universal compatibility with the next-generation of Qi charging bases.

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, IDT stated. The high-efficiency, cost-effective design is intended for high-volume portable devices where battery life and physical size are a primary concern such as in smartphones, tablets and related accessories.

For added control, IDTP9025 is capable of passing communication and power transfer information to a local MCU, 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 sampling to qualified customers and is available in a compact 3 x 2.5mm WLCSP package. The IDTP9025 part number is priced at $2.44 each for volumes of 1,000 units.
