The DGD05791U 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 100V in a bootstrap configuration.

The DGD05791U logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with MCUs. A UVLO for 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 being on at the same time.

Fast and well-matched propagation delays allow a higher switching frequency, enabling a smaller, more compact power-switching design, using smaller associated components. The DGD05791U is offered in the U-DFN3030-10 package and operates over an extended -40°C to +125°C temperature range.
