DGD21084

HALF BRIDGE GATE DRIVER IN SO-14

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.
