Product Description
The TSDMTX-19V3-EVM Evaluation Module is a ready-to-use demonstration platform allowing testing of up to 15
watts of wireless power transmission compliant with the dominant industry WPC/Qi standard.
The transmitter may be coupled with any Qi receiver module to form a complete wireless power transmission
system. For the system designer, a likely choice might be the complementary Semtech TSDMRX-19V/20W-EVM,
which can allow a variety of experiments to easily be performed in order to learn more about the behavior of the
system.
There are a number of other Semtech Receiver EVMs that support different power levels and output voltages, any
of which can be used as they are compatible with Qi standard and therefore are compatible with the TSDMTX-
19V3-EVM transmitter.
In addition, the evaluator can also use any existing Qi compliant product, though the limited access these devices
offer may make the range of experiments that can be performed more limited.
Those who wish to develop their own board, or integrate this functionality into an existing system can use the
EVM as a starting point for their design, as it demonstrates a working model from which to proceed. Toward this
end, all documentation for the EVM is provided to make the process as efficient as possible.
The key technology in the EVM is the Semtech TS80003 integrated circuit, which controls the system and
implements the Qi protocol. Developers can vary the supporting componentry to meet their goals as desired.
In this user guide, an introduction will be provided to the evaluator about how to use the EVM for wireless power
transmission as well as how the TSDMRX-19V/20W-EVM can be used in conjunction with it.
Once the system is set up and working, a selection of tests and activities will be described that the evaluator can
choose to perform.
