DGD0506FN-7

NOT RECOMMENDED FOR NEW DESIGN USE DGD0506A DGD0506 HIGH FREQUENCY HALF-BRIDGE GATE DRIVER WITH PROGRAMMABLE DEADTIME IN DFN3030-10 Description Features The DGD0506 is a high-frequency half-bridge gate driver capable of driving N-channel MOSFETs in a half-bridge configuration. The floating high-side driver is rated up to 50V. • • The DGD0506 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 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 DGD0506 is offered in the V-DFN3030-10 package and operates over an extended -40°C to +125°C temperature range.
