1 / 18 page  DATASHEET P9038 August 1, 2016 1 ©2016 Integrated Device Technology, Inc. 8W, Qi-compliant, Wireless Power Transmitter with Integrated Full Bridge Inverter P9038 Features • 4.5V to 6.9V input operating voltage range, supporting: • USB or AC adapter • USB dedicated charger port (DCP) detection • WPC-1.2.2 compliant for A5 or A11-type coils • Integrated, high-efficiency power stage with low RDS(ON) • Integrated foreign object detection & current sense • Excellent EMI performance eliminates need for EMI filter • Supports up to 8W power transfer to the receiver • Demodulates and Decodes Communication Packets from WPC-compliant Receivers • I2C Interface for EEPROM access • Programmable input over-voltage protection • Programmable soft start • Current limit and over-temperature protection • -40° to +85°C temperature range • 7 x 7 mm 56-VFQFPN package Applications • Furniture • PC peripherals • Rugged electronic gear • Small appliances • Battery-powered electronics Description The P9038 is a WPC-compliant Wireless Power Transmitter for A5 and A11 designs operating from 5V supplies conforming with WPC Specification 1.2.2. 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. The P9038 is available in a compact 7 x 7 mm VFQFPN package, and it is rated for -40° to +85°C temperature range.
