Revolutionizing Battery Safety with SuperQ™ MOSFET Technology

In a world increasingly reliant on high-performance batteries, iDEAL Semiconductor has unlocked new possibilities with the launch of its latest innovation: the SuperQ™ MOSFET. This groundbreaking technology is designed to tackle the delicate balance between safety and efficiency, particularly in high-voltage battery management systems (BMS) that operate at 72V or higher.

Setting New Industry Standards

iDEAL Semiconductor, a leader in high-performance power semiconductors, has unveiled its SuperQ™ MOSFET technology, emphasizing enhanced short-circuit protection capabilities. As electric mobility and high-voltage applications proliferate, effective safeguards against catastrophic failures during external short circuits—where currents can soar into the thousands of amperes—become paramount. The MOSFET discharge switch plays a critical role in isolating the battery during such extreme conditions.

Dr. Phil Rutter, Vice President of Design at iDEAL Semiconductor, highlights the challenges faced by traditional MOSFET designs. He states that these designs often force engineers to choose between achieving ultra-low on-resistance (RDS(on)) for efficiency or maintaining the structural integrity required to withstand massive short-circuit currents. “The SuperQ™ platform eliminates this trade-off. Our patented cell architecture delivers the lowest active-state resistance on the market while providing unparalleled safety margins,” Dr. Rutter notes, enabling designers to create more compact, reliable, and cost-effective battery systems.

Unmatched Short-Circuit Robustness

The technological advancements offered by SuperQ™ are evident in its performance metrics. Initial testing revealed that the iS15M2R5S1T SuperQ MOSFET operates at 150V with an RDS(on) value of 2.5 mΩ while offering a short-circuit withstand capability (SCWC) of 800A. This places it 1.4 times ahead of competing products, which typically record a peak SCWC of 580A at similar specifications. The device's patented structure enhances conduction area, maximizing power density and providing solid structural integrity during periods of high stress.

System-Level Benefits for Designers

SuperQ™'s superior SCWC translates to significant benefits for battery pack designers. Here’s how:

• - Reduction of Components: Each SuperQ device can withstand a higher short-circuit current, allowing engineers to use up to 50% fewer MOSFETs in parallel to meet the same safety requirements. This not only streamlines design but also enhances system reliability.
• - Cost Savings: Fewer components directly lead to substantially lower bill of materials (BOM) costs, simplifying board designs and accelerating the manufacturing process.
• - Increased Efficiency: With an ultra-low RDS(on) value, the SuperQ MOSFET minimizes conduction losses, prolonging battery life and reducing thermal management needs.

The SuperQ product line is now available and includes devices rated up to 200V, catering to battery platforms ranging from 72V to beyond 144V.

Conclusion

iDEAL Semiconductor is not just pushing technological boundaries; it’s reshaping the future of high-voltage battery management systems. With the launch of SuperQ™, iDEAL is well-positioned to support the demand for safer, more reliable, and energy-efficient battery technologies—qualities that will become increasingly vital as the world shifts toward sustainable energy solutions.
