Highly Robust Silicon Power Devices for Battery Management Systems

The accelerating shift to high-voltage battery platforms (72V and above) in e-mobility, drones and power tools is placing unprecedented demands on battery management system (BMS) protection circuitry. This circuitry must protect the battery pack in the event of an external short-circuit, which would see currents spike to thousands of amps in microseconds.

Power devices in these designs must:

  • Provide very high short-circuit withstand capability (SCWC)
  • Turn-off quickly to protect the battery pack
  • Minimize losses and prevent excessive thermals 

SuperQ Technology Delivers a Robustness Advantage

The superior performance of the SuperQ platform is rooted in its proprietary silicon technology. The asymmetrical charge-balanced structure directly addresses the limitations of previous-generation and competing technologies.

SuperQ maximizes power density and reduces RDSon performance trade-offs, and delivers:

  • A wide mesa and wide metal contact
  • A higher current density and current ratings
  • The industry’s lowest on-resistance

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 150 V and 200 V power MOSFET product portfolio for protecting 72 V to 144 V battery packs.
