Product details
Overview
DGD0503FN-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, 430ns typical internal dead time, and operates from -40°C to +125°C with 10V–20V low-side supply and bootstrap-compatible high-side up to 100V. Used in DC-DC converters, motor controls, and Class-D amplifiers.
For engineers reviewing the DGD0503FN-7 datasheet, DGD0503FN-7 pinout, DGD0503FN-7 application, or DGD0503FN-7 equivalent, key selection criteria include bootstrap high-side voltage rating (100V), logic-level compatibility (3.3V TTL/CMOS), output drive strength, internal dead time accuracy, and W-DFN3030-10 thermal performance under high-frequency switching.
Technical Context
The DGD0503FN-7 integrates independent high-side and low-side drivers with Schmitt-triggered logic inputs (HIN/LIN*), undervoltage lockout on both VCC and VB supplies, and fixed 430ns dead-time circuitry to prevent shoot-through. Its floating high-side stage supports bootstrap operation with VS referenced to VB up to 100V offset.
It delivers asymmetric drive capability: 290mA peak source current for HO and 600mA sink for LO, with propagation delays of 680ns (tON, VS = 0V) and 150ns (tOFF, VS = 100V), and rise/fall times under 170ns/90ns into 1nF load - optimized for fast-switching power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 100V max VS-to-VB offset - enables bootstrap operation in 48V–80V bus systems without external level shifters. |
| Output Drive Strength | 290mA source / 600mA sink - sufficient to rapidly charge/discharge 1nF gate capacitance in <100ns. |
| Internal Dead Time | 430ns typical - prevents simultaneous conduction in half-bridge MOSFETs at switching frequencies up to 500kHz. |
| Logic Input Threshold | VIH ≥ 2.5V, VIL ≤ 0.8V at VCC = 10–20V - ensures reliable 3.3V CMOS/TTL interfacing without level translation. |
| Operating Temperature | -40°C to +125°C ambient - supports industrial and automotive under-hood applications with full parameter guarantee. |
| Supply Voltage Range | VCC: 10V–20V; VB referenced to VS - allows flexible low-side bias and robust bootstrap capacitor charging. |
Pinout & Package
Supplied in a thermally enhanced W-DFN3030-10 (Type TH) package - 3.0mm × 3.0mm, 0.75mm height, matte tin terminals, moisture sensitivity level 3, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Low-side and logic supply input | Provides power for internal logic, level shifters, and low-side driver; requires 10–20V with UVLO at 7.4–9.6V. |
| 2 HIN | High-side logic input | In-phase control signal for HO output; Schmitt-triggered for noise immunity and clean edge detection. |
| 3 LIN* | Low-side logic input (active-low) | Complementary (inverted) control for LO; * denotes active-low polarity per datasheet convention. |
| 4,7 NC | No connection | Unbonded pins - must be left floating or tied to COM per layout guidelines; no internal function. |
| 5 COM | Low-side return and logic ground | Common reference for VCC, LIN*, and LO output; must be low-inductance path to minimize ground bounce. |
| 6 LO | Low-side gate drive output | Drives N-MOSFET gate referenced to COM; 600mA sink capability enables fast turn-off of high-Ciss devices. |
| 8 VS | High-side floating supply return | Reference node for high-side driver; swings with half-bridge output; must be routed with minimal loop inductance. |
| 9 HO | High-side gate drive output | Drives high-side N-MOSFET gate referenced to VS; 290mA source current supports rapid turn-on under bootstrap constraints. |
| 10 VB | High-side floating supply input | Connects to bootstrap capacitor top plate; rated for -0.3V to +124V; clamps transients via internal protection. |
Key Features
| Feature | Design Value |
|---|---|
| Floating high-side driver | Supports 100V bootstrap operation without external level-shifting circuitry - reduces BOM count and PCB area. |
| Asymmetric output drive | 290mA HO source / 600mA LO sink - matches typical N-MOSFET gate charge asymmetry for balanced switching transitions. |
| Fixed internal dead time | 430ns typical - eliminates need for external dead-time generation circuitry and associated timing uncertainty. |
| Negative transient tolerance | Outputs withstand -0.3V undershoot on HO/LO - protects against Miller-induced negative spikes during hard commutation. |
| UVLO on dual supplies | Independent VCCUV+ (8.5V typ) and VBSUV+ (6.5V typ) thresholds - prevents erratic switching during brown-out or bootstrap capacitor discharge. |
Applications
| DC-DC Converters | Motor Control Systems |
|---|---|
Use Scenario: Synchronous buck converter in telecom power modules operating at 300kHz with 48V input and 12V/30A output.

IC Role / Device Role / Timing Role: Gate driver per half-bridge leg; accepts PWM signals from MCU and translates to high-current gate pulses with matched propagation delay. Use Value: 680ns tON / 150ns tOFF matching (<60ns skew) minimizes phase current distortion, improving torque ripple by ≤2.3% at 20krpm. |
| Class-D Audio Amplifiers | AC-DC Power Supplies |
Use Scenario: 200W bridge-tied load (BTL) amplifier with >500kHz switching frequency and THD+N <0.05% at full power. IC Role / Device Role / Timing Role: High-speed half-bridge driver delivering clean, low-jitter gate edges to GaN FETs in output stage.

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 |
|---|---|---|---|
| IRS2005STRPBF | Higher 600V high-side rating; 250ns dead time; SOIC-16 package; no 3.3V logic support. | Better suited for 300–400V bus inverters; requires level-shifting for 3.3V MCUs. | Select when >100V high-side swing or through-hole assembly is required; trade off board space and logic compatibility. |
| LM5109BMAX/NOPB | Adjustable dead time (external resistor); 100V rating; 1.2A sink/source; HTSSOP-8 package. | Enables fine-tuned dead time for GaN or SiC; higher drive current supports larger gate charges. | Select when dead time optimization or >600mA drive is needed; accept larger footprint and external component overhead. |
Compared with IRS2005STRPBF and LM5109BMAX/NOPB, the DGD0503FN-7 offers optimal integration for compact 100V-class designs: its W-DFN3030-10 footprint saves >65% board area versus SOIC-16, native 3.3V logic eliminates level shifters, and fixed 430ns dead time simplifies layout while maintaining safety margins at 500kHz.

FAQ
What is the maximum allowable dVS/dt at the VS pin?
The DGD0503FN-7 specifies a maximum dVS/dt of 50 V/ns at the VS pin, verified per Absolute Maximum Ratings. This rating ensures reliable operation during fast-switching events in hard-commutated topologies like LLC or Class-D, preventing false triggering of the high-side driver due to capacitive coupling.
Can LIN* be driven with active-high logic?
No - LIN* is an active-low input per the datasheet; applying a high logic level disables the low-side output. To interface with active-high PWM signals, invert the signal externally or use a logic inverter. The HIN/LIN* pair is strictly complementary and non-reconfigurable.
Is the W-DFN3030-10 package lead-free and RoHS compliant?
Yes - the DGD0503FN-7 uses a fully lead-free, RoHS 3-compliant (2015/863/EU) W-DFN3030-10 package with matte tin finish terminals, halogen- and antimony-free "Green" molding compound, and UL 94V-0 flammability rating.
Does the internal dead time vary with temperature or supply voltage?
No - the 430ns typical dead time is fixed by internal circuitry and remains stable across the full operating range (-40°C to +125°C) and VCC (10–20V). Measured variation is ±120ns over conditions, with min/max values specified as 300ns/550ns in AC Electrical Characteristics.
