Product details
Overview
DGD0547FN-7 from Diodes Incorporated is a high-frequency dual-channel gate driver IC for N-channel MOSFETs in half-bridge configurations, featuring 50V floating high-side capability, 1.5A source/2.5A sink output current, 20ns typical propagation delay, and integrated bootstrap diode - deployed in DC-DC converters and Class D amplifiers requiring compact, high-efficiency switching.
For engineers reviewing the DGD0547FN-7 datasheet, DGD0547FN-7 pinout, DGD0547FN-7 application, or DGD0547FN-7 equivalent, key selection criteria include high-side UVLO threshold (4.5V typ), <5ns delay matching between HO/LO outputs, -40°C to +125°C operating range, and W-DFN3030-10 package thermal resistance (RθJA = 64°C/W).
Technical Context
The DGD0547FN-7 integrates independent high-side and low-side drivers with cross-conduction prevention logic that enforces dead-time by disabling simultaneous HO/LO activation. Its floating high-side stage supports up to 50V VB and tolerates dVS/dt transients up to 50V/ns.
Logic inputs (HIN, LIN, EN) accept 3.3V–5V TTL/CMOS levels with input hysteresis (0.6V typ), while dual UVLO circuits monitor both VCC (4.5V typ turn-on) and VB (4.5V typ turn-on) to safeguard MOSFETs during supply brownouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.5A source / 2.5A sink per channel - enables fast MOSFET turn-on/turn-off with minimal Miller plateau dwell time |
| Propagation Delay | 20ns (typ) HO/LO - supports >1MHz switching in hard-switched topologies without timing skew penalties |
| Delay Matching | ≤5ns max between HO & LO - ensures precise dead-time control critical for half-bridge shoot-through prevention |
| UVLO Thresholds | VCCUV+ = 4.5V, VBSUV+ = 4.5V (typ) - prevents MOSFET operation below safe gate-drive voltage margins |
| Operating Temp | -40°C to +125°C - validated for industrial motor drives and battery-powered tools with ambient thermal stress |
| Quiescent Current | <1µA shutdown, 130µA (typ) ICCQ - minimizes standby power loss in always-on systems like eCig controllers |
| Bootstrap Diode | Integrated VF = 0.67V @ 100µA - eliminates external diode footprint and reduces BOM count in space-constrained layouts |
Pinout & Package
Package: W-DFN3030-10 (Type TH), 3.0mm × 3.0mm × 0.75mm, matte tin terminals, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Low-side and logic supply input | Provides fixed 5–14V bias for internal logic and low-side driver; referenced to COM |
| 2 NC | No internal connection | Unbonded pad - must remain unconnected on PCB to avoid parasitic coupling or thermal mismatch |
| 3 VB | High-side floating supply | Bias input for high-side driver stage; floats with VS and must be ≥VS +5V for proper operation |
| 4 HO | High-side gate drive output | Drives gate of high-side N-MOSFET; swings from VS to VB with 1.5A/2.5A drive strength |
| 5 VS | High-side floating return | Reference node for high-side driver; connects to source of high-side MOSFET and bootstrap capacitor negative |
| 6 EN | Enable logic input | Active-high enable; logic low forces HO/LO low and disables all outputs regardless of HIN/LIN state |
| 7 HIN | High-side logic input | In-phase control signal for HO; accepts 3.3V/5V CMOS/TTL with 0.6V hysteresis for noise immunity |
| 8 LIN | Low-side logic input | In-phase control signal for LO; synchronized with HIN but independently controllable for PWM or phase-shifted operation |
| 9 COM | Low-side and logic ground | Common return for VCC, LO, and logic circuitry; must be low-inductance connection to system ground plane |
| 10 LO | Low-side gate drive output | Drives gate of low-side N-MOSFET; referenced to COM with 1.5A/2.5A drive capability |
Key Features
| Feature | Design Value |
|---|---|
| 50V floating high-side driver | Supports high-side operation up to 50V VB with robust dVS/dt immunity (50V/ns), enabling use in 48V bus systems |
| Cross-conduction prevention logic | Hardware-enforced dead-time prevents simultaneous HO/LO activation - eliminates need for external timing circuitry |
| Internal bootstrap diode | Reduces PCB area by ~1.5mm² vs discrete diode solution and improves reliability by removing solder joint failure mode |
| Ultra-low standby current | <1µA ICCSD enables battery runtime extension in eCig and portable tool applications with frequent sleep/wake cycles |
| Matched propagation delays | ≤5ns HO/LO delay mismatch ensures consistent edge alignment across temperature and supply variations |
Applications
| DC-DC Converters | Class D Power Amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2004STRPBF | Higher 600V high-side rating, no integrated bootstrap diode, 100ns propagation delay | Targeted at AC mains-fed inverters; requires external bootstrap diode and larger layout area | Choose for line-powered industrial inverters where 50V rating is insufficient |
| LM5109BMAX/NOPB | Separate high/low supply pins (VDD/VBS), 1A/1.5A drive, 60ns propagation delay | Designed for automotive-grade 12V systems; AEC-Q100 qualified, no extended temp support beyond +125°C | Choose when AEC-Q100 qualification and automotive PPAP support are mandatory |
Compared with IRS2004STRPBF and LM5109BMAX/NOPB, the DGD0547FN-7 delivers superior high-frequency performance (20ns delay), smaller footprint (W-DFN3030-10), and lower BOM cost via integrated bootstrap diode - making it optimal for space- and efficiency-critical 24–48V portable and industrial power stages.

FAQ
Is DGD0547FN-7 still in active production?
No - Diodes Incorporated has discontinued the DGD0547FN-7 and marked it as obsolete per DS39858 Rev. 5-4 (June 2021). Aetrix Electronics maintains limited legacy stock and offers technical support for migration to functionally aligned alternatives such as the DGD05473, which shares pinout and electrical compatibility.
Can DGD0547FN-7 drive 100V MOSFETs?
No - the DGD0547FN-7's high-side floating supply (VB) is rated for ≤60V absolute maximum, with recommended operation up to 14V above VS. Driving 100V MOSFETs requires gate drivers with ≥100V VB rating, such as the IRS21844 or FAN7382.
What is the purpose of Pin 2 (NC) on the W-DFN3030-10 package?
Pin 2 is a no-connect terminal with no internal bond wire or silicon connection. It must remain unconnected on the PCB layout to prevent unintended coupling, thermal stress concentration, or solder bridging - confirmed in Diodes' mechanical drawing and pin description table.
Does DGD0547FN-7 require an external bootstrap capacitor?
Yes - although it includes an internal bootstrap diode, the DGD0547FN-7 requires an external ceramic bootstrap capacitor (typically 0.1µF X7R) between VB and VS to sustain high-side gate drive during continuous conduction. The internal diode only replaces the external diode, not the capacitor.
