Diodes' 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.
