Higher fault-current capability without increasing on-resistance.
Conduction Loss ⬇
Low RDS(on) reduces I2R losses in the charge and discharge paths, limiting heat during normal operation.
Fault-Current Margin ⬆
High short-circuit current capability supports robust interruption of severe battery fault currents.
Component Count ⬇
SuperQ reduces the number of parallel MOSFETs, saving board space and assembly cost.
SuperQ in Battery Management Systems
SuperQ MOSFETs serve in the charge and discharge protection paths, carrying battery current during normal operation and interrupting current when commanded by the BMS.
Designed for Low Resistance and High Current
SuperQ's wide-mesa technology creates a wide conduction region and wide metal contact. This architecture combines low on-resistance with robust current handling, delivering both benefits in the same MOSFET.
