DGD05473FN-7

DGD05473 HIGH FREQUENCY HIGH-SIDE AND LOW-SIDE GATE DRIVER IN DFN3030-10 Description Features The DGD05473 is a high-frequency gate driver capable of driving Nchannel MOSFETs. The floating high-side driver is rated up to 50V. • • The DGD05473 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with MCUs. UVLO for high-side and low-side will protect a MOSFET with loss of supply. To protect MOSFETs, cross conduction prevention logic prevents the HO and LO outputs from 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. The DGD05473 is offered in the V-DFN3030-10 package and operates over an extended -40°C to +125°C temperature range.
