Description

The DGD0579U 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 DGD0579U 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. To minimize space, an internal bootstrap diode is included and the DGD0579U is offered in the W-DFN3030-10 (Type TH) package and operates over an extended -40°C to +125°C temperature range.
