Drivers

The DGD2103/4 is a high-voltage/high-speed gate driver family capable of driving N-channel MOSFETs and IGBTs in a half bridge configuration. High-voltage processing techniques enable the DGD2103/4’s high side to switch to 600V in a bootstrap operation. The DGD2103/4 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 DGD2103/4 has a fixed internal dead time of 520ns.
