Gallium nitride (GaN) motor drivers

Maximize power efficiency and minimize solution size with gallium nitride (GaN) intelligent power modules (IPMs) and half-bridge motor drivers

Browse by category

Our integrated GaN technology delivers greater than 99% inverter efficiency, significantly enhancing thermal performance and minimizing power loss. Advanced integration and increased power density enable a smaller solution footprint and reduce system-level costs. Ultra-low dead time and propagation delay improve acoustic performance, reduce current harmonics, and enable high-accuracy current sensing. Maximized power efficiency, zero reverse recovery, accurate slew-rate control, and  short-circuit and overcurrent protection improve system reliability and extend motor-drive lifetimes.

Introduction to GaN IPMs

Intelligent power modules (IPMs) built with gallium nitride (GaN) enable higher power density and efficiency compared with traditional silicon metal-oxide semiconductor field-effect transistors (MOSFETs) and insulated gate bipolar transistors (IGBTs). 

Benefits:

  • >99% efficiency in the power stage eliminates the need for cooling components such as heat sinks, improving overall efficiency and reducing motor-driver system size.
  • <150ns dead time and propagation delay, along with higher pulse-width modulation switching frequencies, reduces current distortion to improve acoustic performance.
