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 Motor Drives

iDEAL Semiconductor’s SuperQ architecture redefines the capabilities of silicon in motor drive applications — delivering higher performance using mature, CMOS-compatible processes.

SuperQ’s asymmetric trench structure delivers:
