In this demo, an engineer from Menlo Micro compares the company's single-pole, single-throw (SPST) micromechanical switch to a legacy solid-state device. The MM9200 is a high-power SPST MEMS switch.
Menlo Micro's Ideal Switch technology creates highly reliable micromechanical switches capable of carrying high voltage and high current in a small form factor. The MM9200 offers ultra-low on-state resistance, low leakage current, and high-voltage stand-off, operating at over 1 billion switching cycles.
Unlike MOSFETs, the MM9200 supports bidirectional current between contacts, just like electromechanical relays. The internal dual gates are controlled via the common GATE pin and require a gate bias voltage in relation to the MIDPOINT pin to turn on the switch. Multiple MM9200 devices can be connected in series or in parallel to increase voltage rating or current rating, respectively.
