EZ-PD™ PMG1-B1 applications

A growing number of battery operated products in consumer, industrial, and communications segments are adopting USB-C ports to source power. Infineon offers dedicated solutions to integrate USB-C ports into customers' embedded applications. Typical use cases include smart speakers, cameras, headphones, game consoles, power tools, VR headsets and other portable electronics, and home appliances. As the leader in USB-C end-to-end solutions, Infineon provides a comprehensive portfolio of solutions for USB-C chargers and power adapters.

Why move to USB-C

Over 10 billion USB ports will move to USB-C by 2025: mobiles, notebooks, and cars have already chosen this standard, and so will every common DC power source/sink up to 240 W in just a couple of years. The advantages of USB-C are several: plug orientation and cable direction agnostic, bidirectional power flow using USB PD and negotiable voltage, and power up to 240 W. Moreover, by adopting a universal connector, companies can avoid including proprietary chargers for their product, significantly reducing the production of e-waste and their costs at the same time.
