DGD2181M

HIGH-SIDE AND LOW-SIDE GATE DRIVER IN SO-8

Description

The DGD2181M 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 DGD2181M

’s high-side

to switch to 600V in a bootstrap operation.

The DGD2181M 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.

The DGD2181M is offered in SO-8 package and the operating

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