The DGD2005 is a mid-voltage / high-speed gate driver capable of driving N-Channel MOSFETs and IGBTs in a half-bridge configuration. High voltage processing techniques enable the DGD2005’s high-side to switch to 200V in a bootstrap operation. The 30ns (max) propagation delay matching between the high-side and low-side drivers allows high frequency switching.
The DGD2005 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction. The low-side gate driver and logic share a common ground.
The DGD2005 is available in a space saving SO-8 (Type TH) package and operates over an extended -40°C to +125°C temperature range.
