DGD2304

HALF-BRIDGE GATE DRIVER IN SO-8

Contact Sales

Description

The DGD2304 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 DGD2304’s high side to switch to 600V in a bootstrap operation.

The DGD2304 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction. An internal deadtime of 100ns protects high-voltage MOSFETs from shoot-through.

The DGD2304 is offered in the SO-8 package and operates over an extended -40°C to +125°C temperature range.
