Product details
Overview
DGD0597FUQ from Diodes Incorporated is a high-frequency dual-channel gate driver IC for half-bridge N-channel MOSFET configurations, featuring 40V floating high-side capability, 1.5A source/2.5A sink drive strength, 14ns typical propagation delay, and operation from -40°C to +125°C. It enables compact wireless power chargers and motor drives by supporting fast switching with matched timing and integrated bootstrap diode.
For engineers reviewing the DGD0597FUQ datasheet, DGD0597FUQ pinout, DGD0597FUQ application, or DGD0597FUQ equivalent, key selection criteria include high-side UVLO threshold (3.3V), delay matching (2.5ns typ), logic-level compatibility (3.3V–5V TTL/CMOS), and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The DGD0597FUQ integrates independent high-side and low-side drivers with isolated floating supply (VB/VS) architecture enabling direct control of N-MOSFETs in half-bridge topologies. Its internal bootstrap diode eliminates external component requirements while maintaining 40V high-side offset capability and 50 V/ns dVS/dt immunity.
Logic inputs (HIN/LIN) feature pulldown resistors and support 3.3V–5V logic thresholds with 2.5V VIH min and 1.3V VIL max. UVLO protection operates at 3.4V (±0.4V hysteresis) on both VCC and VBS rails, ensuring safe startup and fault recovery under brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC) | 4.5V to 5.5V - Ensures stable operation with standard 5V logic rails and tight regulation tolerance. |
| High-Side Offset Voltage | Up to 40V - Supports high bus voltages in motor drives and wireless charging without external level-shifting. |
| Output Drive Strength | 1.5A source / 2.5A sink - Delivers fast MOSFET turn-on/off with low RDS(on) and minimal gate charge time. |
| Rise/Fall Time | 7ns / 5ns (CL = 1000pF) - Enables >10 MHz switching frequencies and reduces switching losses in high-efficiency converters. |
| Propagation Delay Matching | 2.5ns typical - Minimizes shoot-through risk in half-bridge operation by tightly aligning HO/LO timing edges. |
| UVLO Threshold | 3.4V ±0.4V on VCC and VBS - Prevents erratic gate drive during undervoltage transients while allowing clean restart. |
| Operating Temperature | -40°C to +125°C - Qualified for under-hood automotive, industrial motor control, and thermally constrained wireless power systems. |
Pinout & Package
V-QFN3030-8 (Standard) package: 3.0mm × 3.0mm, 0.65mm pitch, exposed thermal pad connected to COM. RoHS-compliant, halogen-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VB | High-side floating supply input | Connects to bootstrap capacitor top node; supports up to 50V absolute max and 40V operating offset vs VS. |
| 2 HIN | High-side logic input | TTL/CMOS-compatible with internal pulldown; controls HO output phase-aligned with input signal. |
| 3 COM | Low-side return and substrate connection | Common reference for LO, VCC, and thermal pad; must be low-inductance PCB ground plane connection. |
| 4 LO | Low-side gate driver output | Drives N-MOSFET source-connected to COM; 2.5A sink capability ensures rapid turn-off. |
| 5 VCC | Fixed low-side and logic supply | Powers internal logic and low-side driver; requires local 4.7µF ceramic decoupling near pin. |
| 6 LIN | Low-side logic input | In-phase with LO; internal pulldown prevents floating state during MCU reset or power-up. |
| 7 VS | High-side floating supply return | Reference for high-side driver; tied to high-side MOSFET source; critical for accurate dVS/dt immunity. |
| 8 HO | High-side gate driver output | Drives N-MOSFET gate referenced to VS; 1.5A source current enables fast turn-on despite bootstrap impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | Reduces BOM count and layout area; 650mV forward drop at 100µA enables efficient charge replenishment. |
| Matched propagation delays | 2.5ns typical mismatch between HO and LO paths minimizes dead-time uncertainty and shoot-through margin. |
| High dVS/dt immunity | 50 V/ns rating ensures reliable high-side operation during fast switching transitions in noisy power stages. |
| AEC-Q100 qualification | Validated for automotive applications including temperature cycling, HTOL, and ESD testing per Grade 1 requirements. |
| Logic-level input compatibility | Supports direct interface with 3.3V MCUs and FPGAs without level shifters, reducing system complexity and cost. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2005MTRPBF | Higher 600V high-side rating but slower 60ns propagation delay and no integrated bootstrap diode. | Better suited for line-powered PFC and inverter stages above 400V; less optimal for <100V high-frequency wireless power. | Select when high-voltage isolation is required over timing precision and integration density. |
| LM5109BMAX/NOPB | 5V-only VCC range, 1A/1.5A drive, no AEC-Q100 qualification, and no internal bootstrap diode. | Targeted at cost-sensitive consumer power supplies; lacks automotive qualification and high-speed timing performance. | Choose for non-automotive, lower-frequency (<500kHz) designs where BOM cost outweighs timing accuracy. |
