Wurth Elektronik and STMicroelectronics (hereinafter ST) have joined hands to support high-performance power tools.

ST announced on the 21st that it had jointly developed a demonstration using power tools with Würth Electric.

This design, which efficiently drives low-voltage brushless DC motors, is highly suitable for portable power tool applications. In addition, this design includes all the essential user interfaces required to control the motor's trigger, speed, and direction.

This power tool demo was displayed at the ST and Würth Electron booths at PCIM Europe, a major international trade fair held in Nuremberg, Germany, from May 9 to 11, 2023, attracting the attention of numerous visitors.

This demo is based on the STDES-PTOOL3A reference design, and the Gerber files, Bill of Materials (BoM), schematics, and all other reference materials can be downloaded for free from ST.com.

We introduce ST’s STM32G4 MCU, the STDRIVE101 gate driver and six STL220N6F7 MOSFETs in the driving circuit, and Würth Electron’s WE-CBF SMT EMI suppression ferrite bead 4279271 and WE-LHMI SMT power inductor 74437368330, along with the benefits provided to each application in terms of performance, cost, quality, and ease of implementation.

The software code embedded in the STM32G4 was developed using the STM32 Motor Control Software Development Kit (X-CUBE-MCSDK). This design demonstrates a real-world usage scenario for a battery-operated portable power tool.

ST, a global semiconductor company supporting various electronic applications and customers, and Würth Electron, a passive component manufacturer and ST authorized partner, have built a strong cooperative relationship over the past few years and developed a reference design utilizing each company's most outstanding portfolio.

The two companies will combine ST's active components with Würth Electronik's passive components to provide customers with ready-to-use turnkey solutions or customized solutions.

The collaboration between ST and Würth Electron is yielding synergistic effects, including the integration of Würth Electron components into various ST evaluation boards and the expansion of the success and scope of initial joint projects.

Ricardo De Sa Earp, Senior Vice President of ST’s General Purpose Microcontroller Subgroup, stated, “ST has demonstrated the capabilities of its partnership with Würth Electron by collaborating to jointly develop system solutions that address the requirements of the most demanding and complex applications and by maximizing the performance of its products.”

Alexander Gerfer, CTO of the Würth Electronik eiSos Group, said, “The development of cost-effective, high-quality reference designs that provide the foundation for excellent power tools is another example of successful collaboration with ST.”

This demo is scheduled to be showcased at SPS (Smart Product Solutions) in Nuremberg and at the SIDO exhibitions in Lyon and Paris, France.
