The device expands upon the company’s award-winning wireless power family, offering 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. 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.

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.
