Gate drivers - Applications


Our automotive-qualified gate driver portfolio enables designs across different power levels and topologies seen in hybrid and electric vehicles (HEV/EV).

In HEV/EV designs, our gate drivers help to enable:

  • High power density in small package options
  • Reduced power losses at high switching frequencies through high drive currents and fast timing specs
  • High immunity against noisy environments
  • Consistent performance in noisy environments through negative voltage handling and high CMTI ratings
  • High reliability and longer lifetimes through capacitive isolation technology

Power delivery

The key to advancing power delivery designs is to increase power density without sacrificing reliability.

Our gate drivers accomplish this with every power switch in every topology by:

  • Lowering switching losses through high drive current, low propagation delays, and tight delay matching
  • Decreasing size through small packaging options and integrated isolation
  • Increase reliability through negative voltage handling and capacitive isolation technology

Motor drives

From watts to kilowatts, motor drive systems need to be reliable, compact, and efficient. 

Our gate drivers help accomplish this in mid to high power motor drives by: 

  • Making systems more reliable through both capacitive isolation drivers with high CMTI and working voltages and non-isolated drivers with features such as negative voltage handling and interlock
  • Lowering BOM count and size through integrated isolation and advanced protection features like current sense, desaturation detection, and fault detection
  • Increasing switching efficiency though high drive current and fast switching specs
  • Increasing idle efficiency through enable/disable pins
