Reference Design For High-Speed Vacuum Solution

In a hygiene-centric era, a revolutionary reference design offers cutting-edge technology for efficient, durable, and user-friendly vacuum solutions.


In today’s fast-paced, hygiene-conscious world, the vacuum cleaner is an indispensable tool in our daily lives. As households and businesses increasingly prioritize cleanliness and indoor air quality, there’s a pressing need for vacuum cleaners that are effective in dirt removal and energy-efficient, durable, and user-friendly. Infineon Technologies have launched REF-Vacuum-C101-2ED, a reference design for ready-to-use, low-voltage and high-speed vacuum solution to simplify the design process. The design is based on the company’s state-of-the-art thin-film Silicon-On-Insulator (SOI) technology and cutting-edge motion control engine (MCE 2.0) technology. This configuration facilitates rapid prototyping and accelerates the product’s time to market. The design is fine-tuned for primary low-voltage household devices such as vacuum cleaners, fans, pumps, compressors, and other low-voltage motor-driven applications.

Comprehensive in its design, the board is fortified with all necessary components for sensorless field-oriented control (FOC) and has a dedicated interface for three digital Hall sensors, making it adaptable for various low-voltage and high-current motor applications. The reference design encompasses a variety of features tailored for optimal performance. It incorporates a gate driver IC specifically for MOSFET, ensuring precise control. To safeguard the system, it is equipped with anti-reverse connection protection. Power needs are addressed with 12 V and 3.3 V auxiliary power supplies. User interactivity is enhanced with the inclusion of a VSP speed command potentiometer. Additionally, the design prioritizes safety by integrating over-temperature and overcurrent protection mechanisms. 

The reference design is designed to function with an input voltage ranging between 18 to 30 V DC. It’s optimal for a 6S to 7S Li battery configuration. Its prowess is evident as it can deliver a peak power of 600 W at 25 A with a 24 V DC power input, efficiently managed with an onboard cooling fan. The design further integrates a 3 digital Hall interface and offers a user UART for scripting functions. It comes with overcurrent and over-temperature protections and a fault diagnostic LED output to ensure reliability and safety. Emphasizing precision; it incorporates a low-noise, single-shunt current sampling mechanism. This flexibility ensures it can address specific customer needs, positioning the reference design as a foundational platform for further development or alterations.

Infineon Technologies have tested this reference design. It comes with a Bill of Materials (BOM), schematics, 3D model, Printed circuit board (PCB) layout, etc. You can find additional data about the reference design on the company’s website. To read more about this reference design, click here.
