Menlo Micro showcases scalable MEMS power switch architecture at PCIM 2025

The announcement marked the European debut of the company’s MM9200-based demonstration platform, a significant progress point in MEMS switch innovation for high-efficiency, high-reliability applications.

The demonstration system centres on the MM9200 – a 300V, 10A single-pole single-throw (SPST) MEMS switch. Unlike conventional solid-state relays (SSRs) or electromechanical relays (EMRs), the MM9200 delivers ultra-low on-resistance and metal-on-metal contact, significantly reducing power loss and eliminating the need for heat management compromises. It also offers a smaller footprint and superior performance for space-constrained, power-sensitive designs.

The MEMS approach in action

The live setup at PCIM replicated a use case currently in development for the U.S. Navy: an advanced circuit breaker capable of handling 1,000V and 10,000A. In this design, arrays of MM9200 switches are configured for microsecond-speed protection within 1,000V/125A modules. These modules are assembled into hot-swappable units and scaled in parallel to accommodate higher system power. The architecture demonstrates Menlo Micro’s approach to modularity and scalability in demanding environments.

Thanks to the negligible power dissipation of the Ideal Switch, engineers can develop compact, efficient power control systems without traditional limitations around thermal management. This enables smaller, lighter designs in sectors where space, weight, and reliability are critical—including factory automation, data centres, smart grids, EV charging infrastructure, and building management.

What’s next?

Menlo Micro’s demonstration showed how the alternative approach of MEMS technology can deliver measurable advantages over legacy switching solutions, particularly where compactness, speed, and energy efficiency are essential. The MM9200 platform and its scalable architecture may serve as a blueprint for next-generation circuit protection in a wide range of applications.

The company is now excited to step forward into the spotlight as it continues to scale into the future. Menlo Micro is certainly a one-to-watch in the future as its MEMS technology continues to develop across data centres, power, automotive, and beyond.
