The DGD21814 is a high voltage / high speed gate driver capable of driving N-Channel MOSFETs and IGBTs in a half bridge configuration. High voltage processing techniques enable the DGD21814’s high-side to switch to 600V in a bootstrap operation.

The DGD21814 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) for easy interfacing with controlling devices. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction.

The DGD21814 is offered in SO-14 (Type TH) package and the operating temperature extends from -40°C to +125°C.
