Wireless Charging

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, Microchip’s 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. Microchip also provides many of the analog support pieces for communications, power management and output control to enable a complete system design.

Development Tools

Development Tool


The Automotive Networking Development Board is a low-cost modular development system for Microchip’s 8-bit, 16-bit, and 32-bit microcontrollers targeting CAN and LIN network related applications. The board supports devices using the 100-pin Plug-In Module (PIM) connector, has four mikroBUS™ sockets for MikroElektronika™ Click boards™ and includes an edge connector for backwards compatibility to PICtail™ Plus boards used with the Explorer 16 Development Board.

The LIN Serial Analyzer development tool enables you to monitor and communicate to a Local Interface Network (LIN) bus using a Personal Computer (PC). This is a powerful tool that can be used to send messages, monitor the bus traffic, perform errors checks and filter messages amongst many other features, allowing you to develop and debug the system implementation.

The dsPIC33EV 5V CAN-LIN Starter Kit features the dsPIC33EV256GM106 Digital Signal Controller (DSC) for automotive and motor control applications. The Starter Kit contains serial data ports for CAN, LIN and SENT, a self-contained USB programming/debug interface, and an expansion footprint for flexibility in application hardware development. This board allows you to explore three popular automotive and industrial serial data formats (CAN, LIN and SENT).

The MIC4605 is an 85V half-bridge MOSFET driver that features adaptive-dead-time and shoot-through protection. The adaptive-dead-time circuitry actively monitors the half-bridge outputs to minimize the time between high-side and low-side MOSFET transitions, thus maximizing power efficiency. Anti-shoot-through circuitry prevents erroneous inputs and noise from turning both MOSFETs on at the same time. Additionally, the MIC4605’s adjustable gate drive sets the gate drive voltage to VDD for optimal MOSFET RDS(ON), which minimizes power loss due to the MOSFET’s RDS(ON).

The MAQ5280 Evaluation Board demonstrates the features of the MAQ5280, a high-performance linear regulator, offering a very low-noise output with a very wide input voltage operating range, from 4.5V to 120V DC input voltage.
