TSDMTX-5V2-EVM

Rev1.0

Product Description

The TSDMTX-5V2-EVM Evaluation Module is a ready-to-use demonstration platform allowing testing of

up to 5 watts of wireless power transmission compliant with the dominant industry standards – Qi and

PMA.

The transmitter may be coupled with any Qi or PMA receiver module to form a complete wireless power

transmission system. For the system designer, a likely choice might be the complementary Semtech

TSDMRX-5W-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 all support the Qi and/or PMA standard and therefore are

compatible with the TSDMTX-5V2-EVM transmitter.

In addition, the evaluator can also use any existing Qi or PMA 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 TS80000 integrated circuit, which controls the system and

implements the Qi and PMA protocols. Developers can vary the supporting componentry to meet their

goals as desired.

In this user guide, an introduction will be provided to the evaluator for how to use the EVM for wireless

power transmission as well as how the TSDMRX-5W-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.

LED Behavior

The red and green LEDs on the EVM let the user know what the transmitter is doing as it operates. As

seen in the diagram below, when power is applied, the transmitter initializes as indicated by the green

LED lighting for about a half second. Next, as the transmitter searches for a nearby receiver, no LED is lit,

keeping power to a minimum in this standby state. When a receiver is located the transmitter receives
