DGD1503

HALF-BRIDGE GATE DRIVER IN SO-8

Description

The DGD1503 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 DGD1503

’s high side

to switch to 250V in a bootstrap operation.

The DGD1503 logic inputs are compatible with standard TTL and

CMOS levels (down to 3.3V) to interface easily with controlling

devices. The driver output features high-pulse current buffers

designed for minimum driver cross conduction. DGD1503 has a fixed

internal deadtime of 430ns (typical).

The DGD1503 is offered in the SO-8 (Type TH) package and operates

over an extended -40°C to +125°C temperature range.
