12V Wireless Power
Transmitter IC for TX-A6
P9036B
Description
The P9036B is a highly integrated WPC-compliant wireless power
transmitter IC for power transmitter WPC design TX-A6. This device
operates with a 12Vdc adaptor, and drives an external load directly via
an internal half-bridge. It controls the transferred power by changing the
switching frequency of the half-bridge inverter from 110 kHz to 205 kHz
as specified by the WPC specification for an “A6” transmitter. It
contains logic circuits required to demodulate and decode WPC-
compliant message packets sent by the mobile device to adjust the
transferred power.
The P9036B is an intelligent device, which manages mobile device
detection, and selection of one of the three coils of the A6 transmitter
coil without user supervision. The A6 configuration allows free mobile
device positioning over a wider area than configurations that use a
single coil, detecting a mobile device for charging while minimizing idle
power. Once the mobile device is detected and authenticated, the
P9036B continuously monitors all communications from the mobile
device, and adjusts the transmitted power accordingly by varying the
switching frequency of the internal half-bridge inverter.
The P9036B can optionally support a proprietary back-channel
communication mode, which enables the device to communicate with
IDT’s wireless power receiver solutions. This feature enables additional
layers of capabilities beyond the standard WPC requirements.
The P9036B includes over-temperature/current protection and WPC
compliant Foreign Object Detection (FOD) to protect the base station
from overloading in the presence of a metallic foreign object.
Additionally, it manages fault conditions associated with power transfer
and controls LED outputs to indicate operating status.
