The DGD2003 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 DGD2003’s high side to switch to 200V in a bootstrap operation.
The DGD2003 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices. The driver output features high pulse current buffers designed for minimum driver cross conduction. The DGD2003 has a fixed internal deadtime of 420ns (typical).
The DGD2003 is offered in the SO-8 (Type TH) package and operates over an extended -40°C to +125°C temperature range.
