DGD05463

HIGH FREQUENCY HALF-BRIDGE GATE DRIVER

WITH PROGRAMMABLE DEADTIME

Description

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.
