To expedite the time to market for electric vehicle (EV) chargers, Microchip Technology has introduced three versatile and scalable EV charger reference designs. These designs include a Single-Phase AC Residential charger, a Three-Phase AC Commercial charger with Open Charge Point Protocol (OCPP) and System-on-Chip (SoC), and a Three-Phase AC Commercial charger with OCPP and Display.

Microchip provides most of the essential components for the EV charger reference designs, such as the microcontroller (MCU), analog front-end, memory, connectivity, and power conversion. This comprehensive offering simplifies the integration process, empowering manufacturers to accelerate the launch of new charging solutions.

Joe Thomsen, corporate vice president of Microchip’s digital signal controller business unit, emphasized the company's commitment to supporting customers with ready-to-use reference designs. Thomsen stated, “We aim to assist our customers in reducing design cycles by providing complete solutions like these new EV charger reference designs, along with the necessary hardware, software, and technical assistance.”

The EV charger reference designs from Microchip allow manufacturers to scale their offerings based on the target market, catering to both residential and commercial charging applications. These designs come with full hardware design files and source code, featuring software stacks that are tested and compliant with communication protocols like OCPP.

The Single-Phase AC Residential EV Charger Reference Design is a cost-effective solution tailored for home charging using a single-phase power supply. It incorporates a high-performance energy metering device with automatic calibration, simplifying the production process. Safety features like Protective Earth Neutral (PEN) fault detection and Residual Current Device (RCD) detection are integrated into the design.

Designed for high-end residential and commercial charging stations, the Three-Phase AC Commercial with OCPP and Wi-Fi® SoC EV Charger Reference Design includes OCPP 1.6 stack integration for communication with charging networks and a Wi-Fi SoC for remote management.

Targeting commercial and public charging stations, the Three-Phase AC Commercial with OCPP and Display EV Charger Reference Design prioritizes robust operation, with a complete architecture review compliant with UL 2231 standards. It supports up to 22 kW with bidirectional charging capabilities and features a modular architecture. The design also boasts a durable Graphical User Interface (GUI) with a Thin-Film Transistor (TFT) screen and touch input suitable for harsh environments.

Microchip offers a comprehensive suite of technologies and solutions to simplify the complex and fragmented global EV charging landscape. In addition to the reference designs, Microchip provides hardware, software, and global technical support to streamline the design process.
