Description
The DGD21084 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 DGD21084’s high-side to switch to 600V in a bootstrap operation.
The DGD21084 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. Programmable dead time, by an external resistor, provides more system level flexibility.
The DGD21084 is offered in SO-14 (Type TH) package, the operating temperature extends from -40°C to +125°C.
