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.
50V Floating High-Side Driver
Drives Two N-Channel MOSFETs in a Half-Bridge Configuration
1.5A Source / 2.5A Sink Output Current Capability
Internal Bootstrap Diode Included
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.
Undervoltage Lockout for High-Side and Low-Side Drivers
Programmable Deadtime to Protect MOSFETs
Logic Input (IN and EN) 3.3V Capability
Ultra Low Standby Currents (<1µA)
Extended Temperature Range: -40°C to +125°C
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
Fast and well-matched propagation delays allow a higher switching
frequency, enabling a smaller, more compact power switching design
using smaller associated components. The DGD05463 is offered in
the W-DFN3030-10 (Type TH) and MSOP-10 packages and operates
over an extended -40°C to +125°C temperature range.
