Wireless charging – power transfer

It’s a familiar story: You want to make a call but your smartphone battery has just died. Up until now, you would have had to find the charging cable, connect it to your phone and then plug it into an outlet. Which is all fine. But it can still be a hassle. Especially if you can’t find your cable or the one you have doesn’t fit the jack on your phone. Wireless charging changes all that. It uses electromagnetic fields to transfer power from a transmitter to a receiver application. In short, it charges your battery without a physical connection.

Our portfolio comprises a broad selection of leading semiconductor products address application requirements for wireless charging, ranging from just a few watts up to kilowatts. These products include:

• Best-in-class discrete OptiMOS™ MOSFETS
• StrongIRFET™ MOSFETS
• CoolMOS™ MOSFETS
• Small signal power MOSFETs
• GaN HEMTs for high-speed switching
• Reverse conducting IGBTs
• Voltage and buck regulators for component and bridge supplies
• Gate driver ICs from our EiceDRIVER™ family
• OPTIGA™ Trust Charge, an integrated turnkey solution for authentication, and
• Dedicated microcontrollers

Backed by our end-to-end application expertise, we offer safe and efficient wireless charging solutions for inductive and resonant topologies.

There are many reasons why you should include wireless charging into your application. There are, of course, the obvious ones – you no longer have to plug in your device or worry about plug compatibility issues. But wireless charging is also safer since there is no contact with exposed electrical connectors. What’s more, wireless charging is more reliable in harsh environments such as industrial and outdoor locations because it enables completely sealed system designs. And with wireless charging technology becoming more widespread in public spaces and in private and public transportation, you can quickly and easily charge your devices on the go. You can also charge multiple devices without having to untangle charging cables.
