Product details
Overview
DGD0506FN-7 from Diodes Incorporated is a high-frequency half-bridge gate driver IC designed to drive two N-channel MOSFETs in synchronous buck, motor control, and Class-D amplifier topologies. It features 50V floating high-side capability, 1.25A source / 2.0A sink output current, programmable deadtime (40–560 ns), and operates across –40°C to +125°C. Its integrated bootstrap Schottky diode and TTL/CMOS-compatible 3.3V logic inputs enable direct MCU interfacing in compact DC-DC converters.
For engineers reviewing the DGD0506FN-7 datasheet, DGD0506FN-7 pinout, DGD0506FN-7 application, or DGD0506FN-7 equivalent, key selection criteria include deadtime configurability via external resistor, matched HO/LO propagation delays (<50 ns skew), UVLO thresholds (6.6 V typical), ultra-low standby current (<1 µA), and V-DFN3030-10 thermal performance (RθJA = 64 °C/W).
Technical Context
The DGD0506FN-7 implements independent high-side and low-side drivers with cross-conduction prevention logic that enforces non-overlapping HO and LO outputs. Its programmable deadtime is set by an external resistor on the DT pin, enabling precise timing control across 40–560 ns range depending on RDT value (10 kΩ or 100 kΩ).
It integrates a bootstrap Schottky diode rated for 400 mA pulsed current and supports floating high-side operation up to 50 V with dVS/dt immunity of 50 V/ns. UVLO protection is implemented separately for VCC and VB, with hysteresis (±0.3 V) and thresholds centered at 6.9 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Drive Strength | 1.25 A source / 2.0 A sink - sufficient to rapidly charge/discharge gate capacitance of medium-power MOSFETs in <500 kHz switching applications |
| Programmable Deadtime Range | 40–560 ns - configurable via single external resistor to prevent shoot-through in varied load and layout conditions |
| Propagation Delay Matching | <50 ns max skew between HO and LO - enables precise timing alignment critical for high-efficiency half-bridge operation |
| UVLO Thresholds | VCCUV+/VBUV+ = 6.9 V ±0.3 V - ensures MOSFET gate drive remains disabled until stable supply is established |
| Quiescent Supply Current | <1 µA in shutdown - minimizes system standby power loss in battery-powered tools and eCig devices |
| Operating Temperature | –40°C to +125°C - supports industrial and automotive-adjacent environments without derating |
| Package Thermal Resistance | RθJA = 64 °C/W - enables >400 mW continuous dissipation on standard 2-layer FR-4 PCB |
Pinout & Package
Supplied in the V-DFN3030-10 (Standard) package: 3.0 mm × 3.0 mm × 0.8 mm body with exposed thermal pad, matte tin terminals, and JEDEC-compliant moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Low-side and logic supply input | Provides power for internal logic and low-side driver; must be decoupled near pin with ≥1 µF ceramic capacitor |
| 2 VB | High-side floating supply input | Connects to bootstrap capacitor positive terminal; rated up to +50 V relative to VS |
| 3 HO | High-side gate drive output | Drives gate of high-side N-MOSFET; requires series gate resistor to damp ringing and limit peak current |
| 4 VS | High-side floating supply return | Reference node for high-side driver; connects to source of high-side MOSFET and bootstrap capacitor negative terminal |
| 5 NC | No connect | Internally unconnected; must remain floating or tied to COM per layout guidelines to avoid parasitic coupling |
| 6 DT | Deadtime configuration input | Accepts external resistor to ground to set HO/LO non-overlap interval; 10 kΩ → 70 ns, 100 kΩ → 430 ns typical |
| 7 EN | Enable logic input | Active-high; drives both HO and LO low when logic low; compatible with 3.3 V MCU GPIO |
| 8 IN | Phase control input | In-phase with HO output; inverted internally to generate LO signal; TTL/CMOS compatible down to 3.3 V |
| 9 COM | Low-side and logic ground return | Common reference for VCC, EN, IN, and LO; must be low-inductance connection to PCB ground plane |
| 10 LO | Low-side gate drive output | Drives gate of low-side N-MOSFET; complements HO with programmable deadtime; sinks up to 2.0 A |
| Pad | Thermal substrate connection | Must be soldered to large copper pour tied to COM for thermal and EMI performance; not electrically isolated |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap Schottky diode | Eliminates need for external diode; rated 400 mA pulsed, VF ≤ 0.8 V @ 100 mA - reduces BOM count and layout area |
| Independent UVLO on VCC and VB | Prevents partial drive during brown-out; triggers at 6.6 V falling threshold with 0.3 V hysteresis - avoids MOSFET linear-mode stress |
| Logic-level compatibility | IN and EN accept 3.3 V logic directly - enables seamless interface with modern low-voltage MCUs without level-shifting circuitry |
| Ultra-low shutdown current | <1 µA ICCSD - extends battery life in portable tools and eCig devices during idle periods |
| Matched propagation delays | tON(HO) and tON(LO) differ by ≤50 ns - ensures tight timing control essential for high-frequency ZVS/ZCS topologies |

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 |
|---|---|---|---|
| DGD0506A | Direct replacement with updated process; identical pinout, improved ESD rating (HBM 4 kV), tighter deadtime tolerance (±10% vs ±15%) | Same functional scope but qualified for higher-reliability industrial use; recommended for new designs | Select DGD0506A for production continuity and enhanced robustness; DGD0506FN-7 remains viable for legacy repair or inventory burn-down. |
| IRS2005STRPBF | Higher voltage rating (600 V high-side), no integrated bootstrap diode, fixed 500 ns deadtime, SOIC-14 package | Targeted at line-powered PFC and inverter stages; requires external bootstrap diode and larger board area | Choose IRS2005STRPBF only when >100 V bus operation or higher isolation is required; not drop-in due to package and feature mismatch. |
Compared with DGD0506FN-7, the DGD0506A offers identical functionality with improved manufacturing consistency and ESD resilience, while the IRS2005STRPBF trades integration and size for higher voltage capability-making it unsuitable for low-voltage portable applications where DGD0506FN-7 excels.

FAQ
Is DGD0506FN-7 still in active production?
No - Diodes Incorporated has officially discontinued DGD0506FN-7 and designated it obsolete. The DGD0506A is the approved replacement with identical pinout, improved ESD rating (HBM 4 kV), and tighter deadtime tolerance. Aetrix Electronics maintains limited legacy stock for repair and legacy design support but recommends transitioning to DGD0506A for new designs.
What is the maximum allowable dV/dt on the VS pin?
The DGD0506FN-7 specifies a maximum transient dVS/dt rating of 50 V/ns on the VS pin. Exceeding this may cause false triggering of the high-side driver due to capacitive coupling into the level-shifter circuit. Layout best practices include minimizing loop area between VS, HO, and the high-side MOSFET source, and using local ceramic decoupling between VB and VS.
Can the internal bootstrap diode handle continuous 400 mA current?
No - the 400 mA rating is for pulsed operation (≤10 µs duration). Under steady-state conditions, the internal diode carries only gate-charge replenishment current, typically <10 mA. For applications with high-frequency, high-duty-cycle switching or large gate charges, external current limiting (e.g., pre-bias resistor or external Schottky + series resistor) is required to keep internal diode stress within safe limits.
How does the DT pin affect deadtime asymmetry between HO→LO and LO→HO transitions?
The DT pin sets a single resistor-defined time constant that applies symmetrically to both HO-to-LO and LO-to-HO deadtime intervals. Typical datasheet values show matched tDT (HO-LO) and tDT (LO-HO) within ±50 ns, confirming balanced transition timing. This symmetry eliminates need for separate high/low deadtime tuning in most half-bridge implementations.
