High-Efficiency Silicon Power Devices for Lithium-Ion Motor Control Systems
As demand for e-bikes, e-scooters, light electric vehicles (LEVs), power tools and portable lithium-ion powered systems continues to rise, so does the need for efficient, compact and robust motor drives. These systems must deliver maximum range and torque while fitting into small, cost-sensitive enclosures with limited cooling.
Power devices in these designs must:
- Handle high peak and continuous current
- Survive short circuits, motor stall, and locked-rotor conditions
- Minimize conduction and switching losses to extend battery life
Legacy Silicon Falls Short — WBG Adds Cost
Traditional silicon MOSFETs often lack the efficiency and ruggedness required for modern motor control, especially in 48V–196V lithium-ion battery systems. Meanwhile, wide-bandgap devices may offer an alternative, but at the cost of:
- Higher unit cost
- Increased gate drive complexity
- Lower availability and long-term reliability
- Design-in friction
SuperQTM
A New Standard for BLDC Motor Drives
2X
SuperQ cuts switching losses by more than 2x compared to leading alternatives
6.1mΩ
With a maximum on-resistance of just 6.1mΩ at 200V in a TOLL package, SuperQ delivers the lowest resistance in class
75%
SuperQ utilizes 75% of the die area for conduction, delivering higher current densities and better robustness
144A
Rated up to 144A, SuperQ handles more load than comparable 200V TOLL MOSFETs
