HALF BRIDGE GATE DRIVER IN SO-14
Description
Features
The DIODES™ 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’s 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 package, the operating
temperature extends from -40°C to +125°C.
