Beschreibung

The IDTP9038 is a WPC-compliant Wireless Power Transmitterfor A5 and A11 designs operating from 5V supplies whichconforms with WPC Specification 1.1. Operating in the WPCcompliantmode, the integrated full-bridge inverter supports 8Wpower transfer utilizing the IDTP902X Receiver family, andensures efficient switching with EMI/RFI emissions that arebetter than the requirements of the WPC specification.An embedded microcontroller provides extensive control &application flexibility. In addition to implementing the WPCspecifieddevice identification and a closed-loop control protocolwhich constantly adjusts transmitted power, the IDTP9038features a proprietary back-channel communication modecompatible with other IDT Wireless Power products, providingsecure authentication with data encryption using a Secure HashAlgorithm (SHA) of up to 64 bits.Featuring programmable multi-layer Foreign Object Detectionand built-in Over-Current, Over-Voltage, and Over-TemperatureProtection, the IDTP9038 is extremely easy to use and providesa complete WPC-compliant solution with minimum externalparts count, requiring significantly less board space and lowertotal solution cost than competing products. It is available in acompact 7mm x 7mm VQFN package. A complete Evaluation kitis available with an easy-to-use GUI interface, which allowsusers to quickly verify system performance and implementWPC-compliant designs with minimal effort.
