Wireless charging for personal electronics is a new convenience feature making its way into the automobile. Coupled with hands-free communication, it allows for convenient charging of the phone while in use within the vehicle. With the growing functionality of smartphones within the vehicle, such as it being a source for entertainment, navigation and a wide variety of apps, a convenient method for charging is a differentiating feature in today’s market.

At the core of a wireless charging embedded control system, our Digital Signal Controllers (DSCs) offer advanced features such as multiple Pulse-Width Modulators (PWMs), high-speed Analog-to-Digital Converters (ADCs) and an integrated Digital Signal Processor (DSP). They can support various industry standards for wireless charging, as well as proprietary standards due to the DSC’s computational abilities. We also provide many of the analog support pieces for communications, power management and output control to enable a complete system design.
