Two new compatible evaluation modules (EVMs) are being shipped by Semtech Corporation for prototyping and developing wireless charging solutions for wearable applications. The Semtech TSWITX-G4-EVM is an evaluation platform for the test and experimentation of a wireless charging transmitter based on the Semtech TS80002 Wireless Power Transmitter Controller and TS51231 Driver.

This evaluation module, in conjunction with its compatible receiver, the TSWIRX-5V2-EVM, provides a complete system design solution for low-power, wearable applications. 

Product Line Manager for Wireless Power Products for Semtech’s Power and High Reliability Product group, Ruwanga Dassanayake said: “Easy-to-use wireless charging technology enhances the benefits and consumer experience of wearable devices.”

Dassanayake added: “By introducing this compatible set of EVMs, companies can now evaluate our wireless power products, which feature leading power scalability, design flexibility, and can easily test and develop customized wearable applications in very small form factors.”


The TSWITX-G4-EVM Evaluation Module is a ready-to-use demonstration platform allowing testing of 1.25W of wireless power transmission. The transmitter is coupled with its compatible receiver module, the Semtech TSWIRX-5V2-EVM, to form a complete wireless power transmission system.


TSWIRX-5V2-EVM is a ready-to-use demonstration platform supporting 5V output with up to 250mA for low-power and small form factor wearable applications at an operating frequency of 1MHz.  

Applications include; smart watches, fitness bands, hearing aids, wireless portable keyboards plus more.
