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.
Digital Signal Controllers
Our Digital Signal Controllers (DSCs) include multiple high-resolution Pulse-Width Modulators (PWMs), high-speed Analog-to-Digital Converters (ADCs) and a programmable high-performance core, which are ideal for designing wireless power and/or wireless charging solutions.
Our basic power management solutions include several automotive-grade linear and switched voltage regulators. Linear regulators feature low dropout voltages, ultra-low quiescent currents, wide input voltage ranges, load dump and reverse batter protection. Switching regulators support buck, boost, buck-boost and SEPIC designs from 100 mA to 12A output currents.
- MIC5280 – High performance, low dropout regulator, 25 mA, 120V, adjustable Vout from 1.215 to 5V.
- MCP1790 – 30V, 70 mA, load dump protected linear voltage regulator
- MCP16311 – 30V, 1A PFM/PWM high-efficiency synchronous buck regulator
- MCP16331 – 50V 1A non-synchronous buck regulator
- MCP1725 – 500 mA CMOS LDO with power good and shutdown
Microchip’s portfolio of MOSFET drivers comprises a wide variety of configurations providing for flexibility of design. It includes half-bridge drivers with adaptive dead-time and shoot-through protection, single and dual low-side drivers available in inverting, non-inverting and complementary configurations, and high-side drivers that feature latch up under-voltage lockout protection.
- MIC4605 – Half-bridge, 85V, MOSFET driver
Our portfolio of CAN transceivers includes CAN 2.0, CAN Flexible Data Rate (CAN FD) and CAN Partial Networking (CAN PN) transceivers and supports the ISO 11898 2/5/6, ISO 11898-2:2016 and SAE J2962-2 standards. Features include various wake-up functionalities and exceptional EMC performance even without a common-mode choke. We also offer the industry’s first AEC-Q100 Grade 0 (150°C) qualified CAN transceiver family.
Microchip’s lineup of temperature sensors and switches comprises analog and digital outputs, giving you the flexibility you need for your design. Our automotive-grade temperature sensors are factory calibrated with up to +/-0.5°C accuracy over a temperature range of -40°C to 125°C. And with very small form factors, they provide an ideal solution for temperature sensing without consuming a significant amount of board space.
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.
The Explorer 16/32 Development Kit is a flexible, convenient and ready-to-start development, demonstration and testing platform for 16-bit PIC24 MCUs, dsPIC DSCs and 32-bit PIC32 MCUs. The board accepts Processor Plug-In Modules (PIM) and hardware expansion is possible through the use of PICtail Plus daughter cards and MikroElektronika accessory boards.
This development board for ATA6612C, ATA6613C and ATA6614Q ICs is designed to accelerate programming, prototyping and testing of new LIN designs.
The Three Coil Wireless Power Transmitter is based on the dsPIC33CH128MP506 device and implements a fixed frequency power control topology. The front-end buck-boost control is managed by the dsPIC33CH device. The transmitter includes CAN FD for ease of integration into the automotive environment. The transmitter also enables the implementation of NFC.
The 200W Wireless Power reference design implements a proprietary protocol developed from several years of R&D and granted U.S patents in the field of wireless power. The 200W solution is ideal for applications such as power tools, robotic vacuums, industrial slip rings, small electric vehicles and drones.
