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.

Absolute Maximum Ratings
Stresses above the ratings listed below (Tabl e 1 and Table 2) can cause permanent damage to the P9038. These ratings, which
are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any
other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the
recommended operating temperature range.
Table 1: Absolute Maximum Ratings Summary. (All voltages are referred to ground.)
Table 2: Package Thermal Information
1,2,3
NOTES:
1. The maximum power dissipation is P
D(MAX) = (T
J(MAX
) - T
A
) / JA where T
J(MAX)
is 125°C. Exceeding the maximum allowable power dissipation will result in excessive die temperature,
and the device will enter thermal shutdown.
2. This thermal rating was calculated on JEDEC 51 standard 4-layer board with dimensions 3" x 4.5" in still air conditions.
3. Actual thermal resistance is affected by PCB size, solder joint quality, layer count, copper thickness, air flow, altitude, and other unlisted variables.
