What Can SuperQ Do for Battery Management Systems?
As battery platforms push beyond 72 V in e-mobility, drones, and power tools, battery management systems must contain extreme fault currents that can surge to thousands of amps in microseconds. Protection circuitry now requires power devices that turn off fast, withstand severe short-circuit stress, and manage thermal losses in compact designs.
SuperQ MOSFETs raise the safety and performance ceiling of modern BMS architectures - delivering high short-circuit withstand capability, fast fault turn-off, and low-loss operation for next-generation battery protection.

Higher Power = Higher Voltage
As the market expands into higher power applications, so does the demand for more power and higher battery currents. Increasing battery voltages is necessary to decrease battery currents and requires mid-voltage power switches. SuperQ delivers the ideal 150V and 200V power MOSFET product portfolio for protecting 72V to 144V battery packs.
