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.
