EPIC2ACW01
Qi 1.3 controller for multiple wireless power TXs
Eggtronic EPIC2ACW01 is the EPIC 2.0 Controller designed to manage up to 3 different Qi 1.3 wireless charging spots simultaneously and independently.
The controller includes a proprietary RISC-V 32-bit processor and a rich set of digital and analog peripherals, connected together by a patented internal matrix able to create multiple virtual ASICs dynamically. EPIC2ACW01 is an extremely flexible, highly customizable alternative to substitute with an innovative single controller up to 3 conventional wireless charging ASICs.
EPIC2ACW01 offers a total system cost reduction; thanks to covering multiple charging spots while maintaining a very high and efficient performance.
