【P9038】

8W, Qi-compliant, Wireless Power Transmitter IC

The P9038 is a WPC-compliant Wireless Power Transmitter for A5 and A11 designs operating from 5V supplies conforming with WPC Specification 1.2. Operating in the WPC-compliant mode, the integrated full-bridge inverter supports 8W power transfer utilizing the P902x Receiver family, and ensures efficient switching with EMI/RFI emissions that are better than the requirements of the WPC specification.

To safeguard the device and the system under fault conditions, the P9038 offers resistor programmable Foreign Object Detection, built-in Over-Current protection, and programmable Over-Voltage / Over-Temperature protection. This transmitter is extremely easy to use and provides a complete WPC-compliant solution with minimum external parts count, requiring significantly less board space and lower total solution cost than competing products.
