COMMUNICATION
5W Qi® + PMA Dual-Mode Wireless Power Transmitter EVM
DESCRIPTION
The TSDMTX Evaluation Board is a complete, self-
contained system to measure the performance and
operating characteristics of the wireless power
transmitter reference design. By placing a WPC
Qi® compliant receiver on the transmitter coil, the
EVM implements a 5W Qi® wireless charging
system. By placing a PMA compliant receiver on the
transmitter coil, the EVM implements a 5W PMA
wireless charging system. The EVM will
automatically adjust the charging power, based on
the feedback from the receiver.
The TSDMTX EVM contains a custom controller for
managing the Qi® or PMA protocol and charging
functions. The firmware in the non-volatile
memory of the microcontroller can be modified to
add user-defined functionality for a specific
customer application.
The firmware on the TSDMTX EVM can be updated
via the micro-USB interface on the board. Please
contact Triune Systems for details.
FEATURES
Self-contained WPC 5W Qi® compliant wireless
transmitter
Self-contained PMA 5W Qi® compliant wireless
transmitter
True dual-mode operation automatically determines
correct wireless standard of the receiver
Requires a 19V @ 1A DC input supply
WPC 1.1 foreign object detection (FOD)
LED indicators for power on, charging and error
conditions
APPLICATIONS
Qi® and PMA compliant or non-compliant
wireless charging
o Cell Phones and Smartphones
o Tablets and eReaders
o MP3 Players
o GPS Devices
o Digital Cameras
o Lighting
o Toys

* The EVM is set in the factory for optimum performance using a transmitter coil with inductance of 24uH at
100kHz, such as the TDK WT505090-20K2-A10-G or WT525225-20K2-A1-G. Other transmitter coils can be
used provided the EVM is tuned to resonance at 100kHz by replacing the series resonant capacitors (shown in
diagram). The resonant capacitors should be low-ESR type to prevent excessive PCB heating at high currents.
It is recommended you contact Triune Systems before modifying the EVM.

TSDMTX-19V EVM
Version 1.2

WPC QI® OPERATION
When a WPC Qi® compliant receiver is placed on the transmitter coil, the EVM implements a 5W Qi®
wireless charging system. The EVM will automatically adjust the charging power, based on the feedback
from the receiver. Depending on the type of receiver coil, you may need to place a 1-2mm spacer on the Tx
Coil (plastic or similar non-metallic); the system may operate more reliably with a spacer between the
transmitter and receiver coils. Charging LED will illuminate green for ~2 seconds, and then start flashing
green; this indicates charging is taking place. If the receiver coil moves too far in relation to the transmitter
coil, the Error LED may illuminate solid red, indicating an error condition. If this (or any other error
condition) occurs, remove the receiver from the transmitter, wait for the Charging LED and/or Error LED
to turn off, and then replace the receiver on the transmitter.
The TSDMTX when in Qi® operation contains an algorithm for sensing the presence of additional metal
objects placed on the Tx (foreign object detection). When a metal object is placed on/near the Tx coil
during operation, and if the metal object absorbs too much energy from the system, the Tx will shut down
and the Error LED will flash red.
PMA OPERATION
When a PMA compliant receiver is placed on the transmitter coil, the EVM implements a 5W PMA wireless
charging system. The EVM will automatically adjust the charging power, based on the feedback from the
receiver. Depending on the type of receiver coil, you may need to place a 1-2mm spacer on the Tx Coil
(plastic or similar non-metallic); the system may operate more reliably with a spacer between the
transmitter and receiver coils. Charging LED will illuminate green for ~2 seconds, and then start flashing
green; this indicates charging is taking place. If the receiver coil moves too far in relation to the transmitter
coil, the Error LED may illuminate solid red, indicating an error condition. If this (or any other error
condition) occurs, remove the receiver from the transmitter, wait for the Charging LED and/or Error LED
to turn off, and then replace the receiver on the transmitter.
This default behavior can be changed through firmware modifications.
