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.
Applications
DC-DC Converters
DC-AC Inverters
AC-DC Power Supplies
Motor Controls
