DGD21844M

HALF-BRIDGE GATE DRIVER IN SO-14

Description

The DGD21844M is a high voltage and high speed gate driver capable

of

driving

N-Channel

MOSFETs

and

IGBTs

in

a

half-bridge

configuration.

High

voltage

processing

techniques

enable

the

DGD21844M

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

The DGD21844M 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 deadtime by an

external resistor provides more system level flexibility.

The DGD21844M is offered in the SO-14 package

and the device’s

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