Wide bandgap semiconductor technologies, such as Gallium Nitride Field Effect Transistors (GaN FETs), are used in various power management applications, including high-power motor drives, fast charging adapters, telecom, computing, and even space applications. Renesas provides a range of controllers and drivers specifically designed to harness the advantages of GaN FETs compared to Si FETs.

  • Lower RDSON - Low conduction loss, resulting in higher efficiency and smaller device size.
  • Lower Gate Capacitance - Minimizes switching loss, leading to higher efficiency and smaller device size.
  • Faster Devices - GaN FETs can switch faster, enabling the use of smaller magnetics and leading to compact device size.
  • Wider Bandgap - GaN FETs offer higher reliability for high-temp and radiation applications.

To facilitate the selection process between GaN and Si FETs, Renesas offers pin-to-pin compatible products that can drive both types of FETs for easy comparison.
