DGD21084 - HALF BRIDGE GATE DRIVER

General Description

The DGD21084 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 DGD21084’s high-side to switch to 600V in a bootstrap operation.

Key Features

  • Floating High-side Driver in Bootstrap Operation to 600V.
  • Drives Two N-Channel MOSFETs or IGBTs in a Half Bridge Configuation.
  • Outputs Tolerant to Negative Transients.
  • Programmable Dead Time to Protect MOSFETs.
  • Wide Logic and Low-side Gate Driver Supply Voltage: 10V to 20V.
  • Wide Logic Supply Voltage Offset Voltage: -5V to 5V.
  • Logic Inputs (HIN and LIN.
  • ) 3.3V Capability.
  • Schmitt Triggered Logic Inputs with Internal Pull Down.
  • Undervoltage Lockout.

FETs and IGBTs in a half bridge configuration. High voltage processing techniques enable the DGD21084’s high-side to switch to 600V in a bootstrap operation. The DGD21084 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 dead time, by an external resistor, provides more system level flexibility. The DGD21084 is offered in SO-14 (Type TH) package, the operating temperature extends from -40°C to +125°C.
