IDT推出业界首款双模无线电源接收器IC

Integrated Device Technology, Inc. announced the industry’s first dual-mode wireless power receiver IC that provides compatibility with both the Wireless Power Consortium (WPC) and Power Matters Alliance (PMA) standards. IDT’s innovative receiver bridges the technology gap between competing transmission standards, empowering mobile device and accessory OEMs to use a single bill-of-materials (BOM) to support both WPC and PMA standards.

The IDTP9021 is an enhanced version of IDT’s award winning IDTP9020 wireless power receiver that complies with the PMA Type 1 Interoperability Specification in addition to the WPC “Qi” standard, allowing customers to consolidate multi-chip configurations into a single-chip solution. IDT’s device is the industry’s first to receive pre-certification from the PMA, and is the only solution with demonstrated compatibility between the two most popular magnetic induction-based wireless power standards. The IDTP9021 is ideal for use in a myriad of mobile devices, including smart phones, tablets, MIDs, digital cameras, MP3 players, remote controls, portable medical devices, and other personal electronics.
