Wireless Power    Certified

Active-Semi’s WPC Qi-Certified (version 1.1.2) single-IC based wireless power transmitter solution provides customers with the highest efficiency and lowest stand-by power design available today. The solution works for charging 5W USB powered devices such as, smart phones, mobile devices and portable electronics. This solution also offers the smallest BOM count to reduce the design footprint.

Active-Semi WPC Solution kit EP5220HPA11-1 features PAC5220WP Power Application Controller™ IC which handles all functions of wireless charging including receiver selection & identification, communication & control, power transfer, guided placement through blinking LED, and audio feedback using a piezoelectric buzzer. It also monitors input and output power for load regulation, uses WPC version 1.1 Foreign Object Detection (FOD), and provides over-current and over-temperature protection. 

The turnkey solution and reference design comes with preloaded firmware for power transfer, protection, guided positioning and other functions to perform right out-of-box, and allow customers to perform fast prototyping of their end-product. In addition, the preloaded firmware also allows customization of user features, enabling customers to differentiate their end-products.

Power Application Controller™ IC technology, which is at the heart of this solution, also offers excellent scalability to other WPC configurations, is capable of supporting much higher power levels beyond 5W, and is also suitable for implementing other standards such as PMA using the same platform.

EP5220HPA11-1 and PAC5220WP IC from PAC™ IC Family are now in production. EP5220HPA11-1 is our High Performance BOM solution and the EP5220LCA11-1 is our Low-Cost BOM solution.
