Product details
Overview
DGD0504FN-7 from Diodes Incorporated is a 100V half-bridge gate driver IC designed to drive two N-channel MOSFETs or IGBTs in high-side/low-side configurations. It features 290mA source / 600mA sink output current, fixed 430ns internal deadtime, and bootstrap-capable high-side operation up to 100V. It operates across –40°C to +125°C and supports 3.3V–5V logic inputs for use in DC-DC converters and motor control inverters.
For engineers reviewing the DGD0504FN-7 datasheet, DGD0504FN-7 pinout, DGD0504FN-7 application, or DGD0504FN-7 equivalent, key selection criteria include high-side floating voltage capability (VB up to +124V), propagation delay matching (≤60ns), undervoltage lockout thresholds (VCCUV+ = 8.5V typ), and W-DFN3030-10 thermal resistance (RθJA = 64°C/W).
Technical Context
The DGD0504FN-7 integrates independent high-side and low-side drivers with Schmitt-triggered TTL/CMOS-compatible inputs (IN and SD*), enabling robust noise immunity and direct microcontroller interfacing. Its bootstrap architecture supports VS offset up to 100V with dVS/dt tolerance of 50V/ns.
Internal protection includes VCC and VBS undervoltage lockout (VCCUV− = 7.8V typ, VBSUV+ = 6.5V typ), negative transient-tolerant outputs, and fixed deadtime (300–550ns) to prevent shoot-through in half-bridge topologies used in Class D amplifiers and AC-DC power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | +124V max VB - enables 100V bus applications with 24V margin for transients |
| Output Drive Strength | 290mA source / 600mA sink - sufficient to rapidly charge/discharge 1nF gate capacitance in <100ns |
| Propagation Delay Matching | ≤60ns HO/LO tDM - ensures symmetrical switching timing critical for reduced EMI in inverters |
| Fixed Deadtime | 430ns typical - prevents cross-conduction without external timing components |
| Logic Input Compatibility | 3.3V–5V TTL/CMOS - allows direct interface with modern MCUs and DSPs without level-shifting |
| Operating Temperature | –40°C to +125°C - supports under-hood automotive and industrial power supply environments |
| Thermal Resistance | RθJA = 64°C/W - requires minimal PCB copper area for thermal management at 0.4W dissipation |
Pinout & Package
Package: W-DFN3030-10 (Type TH), 3.0mm × 3.0mm × 0.75mm, matte tin terminals, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Logic and low-side supply input | Accepts 10–20V; powers internal logic and LO driver; monitored by VCCUV lockout |
| 2 IN | Phase-controlled logic input | In-phase with HO output; Schmitt-triggered for noise immunity; compatible with 3.3V/5V logic |
| 3 SD* | Active-low shutdown input | Pulls both HO and LO low when asserted; enables system-level fault response |
| 4, 7 NC | No internal connection | Must remain unconnected; no PCB trace or solder mask opening required |
| 5 COM | Low-side return and logic ground | Common reference for VCC, IN, SD*, and LO; must be low-impedance path to minimize ground bounce |
| 6 LO | Low-side gate drive output | Drives N-MOSFET gate referenced to COM; 600mA sink capability reduces turn-off time |
| 8 VS | High-side floating supply return | Reference node for high-side driver; tracks switching node voltage during bootstrap operation |
| 9 HO | High-side gate drive output | Drives N-MOSFET gate referenced to VS; 290mA source capability ensures fast turn-on |
| 10 VB | High-side floating supply input | Connected to bootstrap capacitor; supplies HO driver; rated to +124V absolute maximum |
Key Features
| Feature | Design Value |
|---|---|
| Floating high-side driver | Supports VS offset up to 100V with 50V/ns dVS/dt immunity - enables reliable operation in hard-switching inverters |
| Integrated deadtime | 430ns fixed internal delay - eliminates need for external RC timing networks and reduces BOM count |
| Negative transient tolerance | Outputs withstand –5V undershoot on VS/COM - protects against Miller-induced ringing in high-dV/dt environments |
| Undervoltage lockout | Independent VCCUV (8.5V typ) and VBSUV (6.5V typ) detection - prevents erratic switching during brownout conditions |
| Schmitt-trigger inputs | Hysteresis ≥1.7V on IN/SD* - rejects >100mV noise spikes common in noisy power stage environments |
Applications
| DC-DC Converters | Motor Control Inverters |
|---|---|

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 |
|---|---|---|---|
| IRS2004PBF | SOIC-8 package; higher RθJA (80°C/W); no integrated deadtime - requires external timing network | Limited to lower-power (<100W) designs due to thermal constraints and layout complexity | Select when legacy SOIC footprint compatibility is required and board space permits external deadtime circuitry |
| LM5109BMAX/NOPB | WQFN-16 package; 120V VB rating; adjustable deadtime via external resistor; higher ICCQ (1.2mA) | Better suited for high-reliability industrial systems requiring programmable timing and extended voltage margin | Select when design flexibility (adjustable deadtime) and 120V headroom outweigh cost and quiescent current penalties |
Compared with IRS2004PBF and LM5109BMAX/NOPB, the DGD0504FN-7 offers superior thermal performance (64°C/W), eliminates external deadtime components, and delivers optimal balance of integration, size, and 100V capability for space-constrained 100–500W power stages.

FAQ
What is the minimum recommended bootstrap capacitor value for DGD0504FN-7 in a 100kHz application?
The datasheet specifies a minimum 0.1µF ceramic capacitor for stable bootstrap operation. At 100kHz with 50% duty cycle, a 0.22µF X7R 25V capacitor is recommended to maintain >6.5V VBS under worst-case load and temperature, ensuring reliable high-side conduction without UVLO triggering.
Can DGD0504FN-7 drive IGBTs with gate charge exceeding 100nC?
Yes - with 600mA sink and 290mA source peak current, the DGD0504FN-7 can fully switch IGBTs up to ~120nC Qg at 100kHz, assuming gate resistor ≤10Ω. For >120nC devices, external gate buffers or parallel drivers are advised to meet required dV/dt and switching loss targets.
How does the DGD0504FN-7 handle negative voltage transients on the VS pin?
The device tolerates –5V undershoot on VS relative to COM, verified per datasheet Absolute Maximum Ratings. This protects against Miller-induced negative spikes during high dV/dt switching events, eliminating need for external clamping diodes in most 100V-class designs.
Is the W-DFN3030-10 package suitable for reflow soldering in lead-free processes?
Yes - the W-DFN3030-10 (Type TH) package is qualified for lead-free reflow per J-STD-020 Moisture Sensitivity Level 3, with peak temperature support up to +260°C. Recommended profile follows IPC/JEDEC J-STD-020D, including preheat, soak, and controlled ramp rates to avoid package cracking.
