Semtech TSWIRX-LI-EVM
The Semtech TSWIRX-LI-EVM is an evaluation platform for the test and experimentation of a wireless charging receiver based on the Semtech TS51223 fully-integrated IC for Wireless Power Receiver and SC810 linear sigle-cell Li-ion battery charger. This evaluation module, in conjunction with its compatible transmitter TSWITX-G2-EVM, provides a complete system solution for low power transmission, receiving and charging for wearable devices.
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.
