    Diode’s High-Frequency Gate Drivers

    Diodes’ DGD05473 high-frequency gate driver is capable of driving N-channel MOSFETs.Image of Diodes' DGD05473 High-Frequency Gate Driver The floating high-side driver is rated up to 50 V. The device logic inputs are compatible with standard TTL and CMOS levels (down to 3.3 V) to interface easily with MCUs. UVLO for high- and low-side protects a MOSFET from supply loss. 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 operates over an extended temperature range of -40°C to +125°C and is available in a U-DFN3030-10 package.
