Wireless power evaluation kits for wearable applications

October 14, 2016 // By Graham Prophet
Semtech is shipping two new, compatible evaluation modules (EVMs) 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.


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 250 mA for low-power and small form factor wearable applications at an operating frequency of 1 MHz.


Use them in smart watches, fitness bands and jewellery; hearing aids; health monitors; wireless portable keyboards, and toys.
