DGD21844M Datasheet Half-bridge Gate Driver

Manufacturer: Diodes Incorporated

Overview: DGD21844M HALF-BRIDGE GATE DRIVER IN SO-14.

General Description

The DGD21844M 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 DGD21844M’s highside to switch to 600V in a bootstrap operation.

The DGD21844M logic inputs are patible with standard TTL and CMOS levels (down to 3.3V) for easy interfacing with controlling devices.

Key Features

  • Floating High-Side Driver in Bootstrap Operation to 600V.
  • Drives Two N-Channel MOSFETs or IGBTs in Half Bridge Configuration.
  • 1.4A Source / 1.8A Sink Output Current Capability.
  • Outputs Tolerant to Negative Transients.
  • Programmable Deadtime to Protect MOSFETs.
  • Wide Low-Side Gate Driver and Logic Supply: 10V to 20V.
  • Wide Logic Supply Voltage Offset Voltage: -5V to 5V.
  • Logic Input (IN and SD.
  • ) 3.3V Capability.
  • Schmitt Triggered Logic Inputs with Int.
