DGD2108

HALF-BRIDGE GATE DRIVER IN SO-8 (TYPE TH)

Description

The DGD2108 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 DGD2108

’s high-side

to switch to 600V in a bootstrap operation.

The DGD2108 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. Internal deadtime

protects high-voltage MOSFETs.

The DGD2108 is offered in SO-8 (Type TH) package, the operating

temperature extends from -40°C to +125°C.
