WPS Solution for Wearable

Single chip for both TX and RX solution

Why choose Direct Charge?

Eliminating the requirement of external battery chargers and improving system efficiency, PCB space and cost.

Voltage Source Direct Charge(Pre-Chg/CC/CV)

The RT1653 Multi-Mode TX Tester

The receiver module with load capacity can be easily configured as various WPC power modes and different load characteristics, including: BPP, EPP, PPDE and fixed frequency RX. The LED display provides the information of RX output voltage, current, power level and frequency. It can be used as a RX test tool in the TX development stage or a burn-in tool companion with TX in the production phase.
