Description

The DGD0590A 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 the provides a 5V gate drive to the MOSFETs.

The DGD0590A 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 DGD0590A 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

  • High-Side 1.0A Source / 1.0A Sink and Low-Side 1.0A Source / 3.0A Sink Output Current Capability
  • Internal Bootstrap Diode Included
  • 3.4V UVLO with 0.4V Hysteresis
  • Fast Rise and Fall Times (27ns/17ns) with 3nF Load
  • Propagation Delay Typical of 16ns for High-Side and 12ns for Low-Side
  • Extended Temperature Range: -40°C to +125°C

Application(s)

  • Wireless Power Charger
  • Motor Drive
  • Logic Level MOSFET Gate Driver
