Description

The DGD0597FUQ is a high-frequency, high-side and low-side gate driver capable of driving N-channel MOSFETs in a half-bridge configuration. The floating high-side driver is rated up to 40V and provides a 5V gate drive to the MOSFETs.

The DGD0597FUQ logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with MCUs. A UVLO will protect ICs and MOSFETs with loss of supply.

Fast and well-matched propagation delays allow a higher switching frequency, enabling a smaller, more compact power switching design, using smaller associated components. The DGD0597FUQ is offered in the V-QFN3030-8 package and operates over an extended -40°C to +125°C temperature range.

Feature(s)

  • 40V Floating high-side driver
  • Low VCC operating voltage: 4.5V to 5.5V
  • Drives two N-channel Logic Level MOSFETs in a half-bridge configuration
  • 5A source / 2.5A sink output current capability
  • Internal bootstrap Diode included
  • 4V UVLO with 0.4V hysteresis
  • Fast rise and fall times (7ns/5ns)
  • Propagation delay typical of 14ns
  • Delay matching typical of 2.5ns
  • Extended temperature range: -40°C to +125°C
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony free. “Green” Device (Note 3)
  • The DGD0597FUQ is suitable for automotive applications requiring specific change control; this part is AEC-Q100 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. https://www.diodes.com/quality/product-definitions/
