The DGD0579UFNQ is a high-frequency, high-side and low-side gate driver with internal bootstrap diode capable of driving N-channel MOSFETs in a half-bridge configuration. The floating high-side driver is rated up to 100V in a bootstrap configuration.

The DGD0579UFNQ logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with MCUs. A UVLO for the high side and low side will protect MOSFETs with loss of supply. Cross conduction prevention logic also protects MOSFETs by preventing the HO and LO from being on at the same time.

Fast and well-matched propagation delays allow for a higher switching frequency, which enables a smaller, more compact power switching design that uses smaller associated components. To minimize space, an internal bootstrap diode is included. The DGD0579UFNQ is offered in the U-DFN3030-10 package and operates over an extended -40°C to +125°C temperature range.
