Isolated Gate Drivers

Ultra-High CMTI Isolated Gate Drivers with Best Propagation Delay Matching

Isolated gate drivers enable low-voltage microcontrollers to safely switch high-voltage power transistors on and off. Apart from isolation, safe switching of high-speed Silicon-carbide (SiC) and Gallium-Nitride (GaN) transistors places an extra requirement on isolated gate driver ICs: high common-mode transient immunity (CMTI). Our isolated gate driver ICs have the highest level of CMTI, 300kV/µs (typical), and are designed to increase the robustness and efficiency of inverter and motor control applications that use these transistor technologies.

Key features include:

  • Integrated digital galvanic isolation, based on our proprietary process technology, for a withstand voltage rating of 3kVRMS for 60 seconds increases safety.
  • Highest propagation delay matching (5ns, max) reduces dead time to increase efficiency.
  • Adjustable UVLO allows for cooler operation of power transistors, improving reliability.
