DGD05473FNQ
HIGH FREQUENCY HIGH-SIDE AND LOW-SIDE GATE DRIVER IN U-DFN3030-10
Description
Features
The DIODES™ DGD05473FNQ is a high-frequency gate driver
capable of driving N-channel MOSFETs. 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
Undervoltage Lockout for High-Side and Low-Side Drivers
Delay Matching Maxmimum of 5ns
The DGD05473FNQ 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 protects a MOSFET with loss of supply. To
protect MOSFETs, cross conduction prevention logic prevents the HO
and LO outputs from being on at the same time.
Propagation Delay Typical of 20ns
Logic Input (HIN, LIN 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)
The DGD05473FNQ is suitable for automotive applications
requiring specific change control; this part is AEC-Q100
qualified, PPAP capable, and manufactured in IATF 16949
certified facilities.
Fast and well-matched propagation delays allow a higher switching
frequency, enabling a smaller, more compact power switching design,
using smaller associated components. An internal bootstrap diode is
included to minimize space. The DGD05473FNQ is offered in the
U-DFN3030-10 package and operates over an extended
-40°C to +125°C temperature range.
