Product Description - Semtech TSWIRX-LI-EVM User Manual

Product Description

The The TSWIRX-LI-EVM Evaluation Module is coupled with its compatible transmitter module, the
Semtech TSWITX-G2- EVM, to form a complete wireless power transmission system, to directly chare a
single cell Li-ion battery for approximately 300mA of charging current.
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 TS51223, which is a fully-integrated wireless power
receiver for low-power, wearable applications that require a space-saving solution. Its 1 MHz switching
frequency enables the use of small inductive components resulting in minimal board space and reduced
costs. It integrates a wide range of protection circuitry including input supply under-voltage lockout, output
voltage soft start, current limiting, and thermal shutdown. The SC810 is a linear sigle-cell Li-ion battery
chager, which can provide a programmable charge current and constant 4.2V 1% regulation.
Once the system is set up and working, a selection of tests and activities will be described that the
evaluator can choose to perform.
