Integrated Device Technology has launched a 15 W wireless power chipset featuring a bi-directional communication channel between the transmitter and receiver. The communication channel enables customers to authenticate a wirelessly-charged receiver device with a specific charging transmitter base and to transfer data without any additional hardware. This is the first widely available 15W solution offering proprietary pairing of transmit and receive solutions for myriad wireless power applications.
The IDT P9242-R3 and P9221-R3 are 15W wireless power transmitter and receiver ICs, respectively, that are included on the transmitter and receiver boards in the WP15WBD-RK Evaluation Kit. In-band, bi-directional communication is achieved by communicating signals between the wireless power coils using IDT's embedded microprocessor technology combined with proprietary algorithms – no additional coils, antennas, or components are required.
The bi-directional evaluation kit adds bi-directional communication to IDT's standard, WPC 1.2-compliant, 15W transmitter P9242-R3 and receiver P9221-R3 evaluation kits without compromising any existing features. The solution delivers industry-leading power conversion efficiency of over 87% from transmitter input to receiver output.
The WP15WBD-RK wireless power evaluation kit includes easy-to-use reference boards and comprehensive design support collateral - easing system integration and enabling immediate prototyping.
