Gate drivers - Applications
HEV/EV
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

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
