iDEAL Semiconductor Introduces SuperQ™ MOSFETs

iDEAL Semiconductor, a leading developer in high-performance silicon chips, has announced the launch of its innovative SuperQ™ MOSFET technology. This new development is specifically designed to address the crucial balance between safety and efficiency in high-voltage battery management systems (BMS), particularly in systems requiring 72 volts or more.

The introduction of this technology arrives at a critical time, as the adoption of high-voltage batteries in electric mobility, drones, and professional power tools is increasing rapidly. With these advances comes heightened risk, particularly concerning the potential for catastrophic failures during external short circuits, which can lead to currents exceeding several thousand amps. The discharge MOSFET serves as the sole component responsible for isolating the battery under such extreme conditions, highlighting the necessity for robustness in high-performance batteries.

"In high-performance batteries, durability is paramount," commented Dr. Phil Rutter, VP of Design at iDEAL Semiconductor. "Traditional MOSFET designs require a trade-off between achieving an incredibly low RDS(on) for efficiency and maintaining the structural integrity necessary to withstand massive short-circuit currents. The SuperQ™ platform eliminates this compromise. Our proprietary cell structure offers the lowest on-resistance on the market, coupled with unmatched safety margins, allowing developers to create smaller, more reliable, and cost-efficient battery systems."

Unparalleled Short-Circuit Strength

The SuperQ series features a remarkable short-circuit withstand capacity (SCWC) of 800A with the iS15M2R5S1T model. Internal testing has confirmed this significant performance advantage when pitted against a leading competitor:


The SuperQ device demonstrated a 1.4 times higher short-circuit withstand strength compared to its closest competition. This outstanding performance stems from a proprietary cell structure featuring a wider conduction path that maximizes both power density and structural integrity under extreme load.

Direct Benefits for Developers

This superior SCWC translates into significant advantages at the system level for battery pack developers:

1. Reduced Component Count: Since each SuperQ device can handle substantially higher short-circuit currents, developers can employ up to 50% fewer MOSFETs in parallel to meet the same safety requirements.
2. Cost Savings: The decrease in component numbers and system complexity leads to a notable reduction in the overall bill of materials (BOM) and simplifies the printed circuit board layout.
3. Efficiency: Maintaining an impressively low RDS(on) of 2.5mΩ minimizes conduction losses, extends battery life, and reduces the need for extensive heat management solutions.

The SuperQ portfolio is now available with devices supporting voltages up to 200V, catering to battery platform applications ranging from 72V to over 144V. Further details and a white paper covering its applications in battery management systems can be accessed at iDEAL Semiconductor’s website.
