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.
