Semtech TS51224 Power Receiver & Battery Charger
Semtech TS51224 Power Receiver and Battery Charger is designed for low-power and wearable applications that need a cost-effective and space-saving solution. The TS51224 charger IC can operate as a single-chip wireless power receiver or in conjunction with a wireless power-controller or application microcontroller to support wireless charging standards. A high-efficiency rectifier converts the input AC power signal to a DC output level for powering an integrated data modulator and a step-down DC-DC converter.
