DGD05473FNQ

HIGH FREQUENCY HIGH-SIDE AND LOW-SIDE GATE DRIVER IN U-DFN3030-10

Description

The DGD05473 is a high-frequency gate driver capable of driving N-

channel 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 protects 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

U-DFN3030-10

package

and

operates

over

an

extended

-40°C to +125°C temperature range.
