DGD21 Gate Drivers

Diodes’ high-voltage/high-speed gate drivers capable of driving N-Channel MOSFETs and IGBTs in half-bridge or full-bridges

Image of Diodes' DGD21 Gate DriversDiodes' DGD21xxx gate drivers provide a simple means of switching power MOSFETs and IGBTs in half-bridge and full-bridge configurations. Featuring both high-side and low-side output drive capability with simple logic level input enables an easy interface between the controller and the power MOSFET / IGBT switches. Supporting up to 600 V via a floating high-side driver allows operation on high-voltage rails commonly used in power supplies, motor drive, and DC-AC inverters. Encompassing self-protection features: such as fixed dead-time delay to evade shoot-through issues; Schmitt triggered inputs to avoid false triggering; gate drive tolerance to negative transients caused during high dv/dt switching; and undervoltage lockout (UVLO) protection on the VCC supply to avoid malfunction under low supply voltage.

Features and Benefits
  • Fast switching
    • Enabling more efficient switching under high-frequency operation
  • Low quiescent current
    • Improved standby efficiency with a low quiescent current consumption
  • Logic level input
    • Can be driven directly from μC or other IC with 3.3 V logic level
  • Dead-time and matched delays
    • To protect the MOSFET / IGBT from shoot through
Applications
  • Motor drive >100 W AC and DC motors including BLDC, PMSM, induction motors:
    • White goods: washing machines, refrigerators, air conditioners
    • Industrial automation
    • Drones, RC cars, and planes
    • Battery operated vehicles
  • Power supplies offline AC and DC SMPS with half-bridge and full-bridge topologies:
    • Server, telecom PSU
    • LED and LCD TV 
  • DC-AC inverters
    • Solar, wind and fuel cells
