DGD05463FN-7

DGD05463 HIGH FREQUENCY HALF-BRIDGE GATE DRIVER WITH PROGRAMMABLE DEADTIME Description Features The DGD05463 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 DGD05463 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, which enable a smaller, more compact power switching design using smaller associated components. The DGD05463 is offered in the W-DFN3030-10 and MSOP-10 packages and operates over an extended -40°C to +125°C temperature range.
