Description

The DIODES™ DGD1504 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 DGD1504’s high side to switch to 250V in a bootstrap operation.

The DGD1504 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices. The driver outputs feature high-pulse current buffers
designed for minimum driver cross conduction. The DGD1504 has a fixed internal deadtime of 430ns (typical).

The DGD1504 is offered in the SO-8 (Type TH) package and operates over an extended -40°C to +125°C temperature range.

Feature(s)

  • Floating High-Side Driver in Bootstrap Operation to 250V
  • Drives two N-Channel MOSFETs or IGBTs in a Half Bridge Configuration
  • 290mA Source / 600mA Sink Output Current Capability
  • Outputs Tolerant to Negative Transients
  • Internal Dead Time of 430ns to Protect MOSFETs
  • Wide Low-Side Gate Driver Supply Voltage: 10V to 20V
  • Logic Input (IN and SD*) 3.3V Capability
  • Schmitt Triggered Logic Inputs
  • Undervoltage Lockout for VCC (Logic and Low Side Supply)
  • Extended Temperature Range: -40°C To +125°C

Application(s)

  • DC-DC Converters
  • DC-AC Inverters
  • AC-DC Power Supplies
  • Motor Controls
  • Class D Power Amplifiers
