Product details
Overview
DGD0579UFN-7 from Diodes Incorporated is a high-frequency dual-channel gate driver IC for half-bridge N-MOSFET configurations, featuring integrated bootstrap diode, 100V floating high-side capability, 1.5A source / 2.5A sink output current, and 60ns typical propagation delay. It enables compact, high-efficiency DC-DC converters and motor control stages operating across –40°C to +125°C.
For engineers reviewing the DGD0579UFN-7 datasheet, DGD0579UFN-7 pinout, DGD0579UFN-7 application, or DGD0579UFN-7 equivalent, key selection criteria include bootstrap-diode integration, <10ns HO/LO delay matching, dual UVLO protection (VCC & VB), TTL/CMOS-compatible 3.3V logic inputs, and W-DFN3030-10 thermal performance (RθJA = 64°C/W).
Technical Context
The DGD0579UFN-7 implements independent high-side and low-side drivers with cross-conduction prevention logic that enforces dead-time between HO and LO outputs. Its floating high-side stage supports up to 100V offset (VS) with dVS/dt immunity of 50 V/ns and internal bootstrap diode (VF = 0.6–1.75 V, IF = 100µA–100mA).
Logic inputs (HIN, LIN, EN) accept 3.3V–5V TTL/CMOS levels with 0.7V hysteresis; UVLO thresholds are VCCUV+ = 5.2V (typ), VCCUV− = 4.7V (typ), VBSUV+ = 4.9V (typ), and VBSUV− = 4.5V (typ). Propagation delays are tightly matched (≤10ns max difference) to support >1 MHz switching in resonant topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 100V max VS offset - enables use with 60V–80V bus systems in half-bridge buck or inverter stages |
| Output Drive Strength | 1.5A source / 2.5A sink - sufficient to rapidly charge/discharge 1–5nF gate capacitances at ≥500kHz |
| Propagation Delay | 60ns typ (HO/LO) - supports stable PWM operation up to 1.5MHz with margin for timing skew |
| Delay Matching | ≤10ns max difference - minimizes shoot-through risk without external dead-time circuitry |
| Logic Input Compatibility | 3.3V–5V TTL/CMOS - direct interface with STM32, PIC, ESP32, and other modern MCUs |
| Quiescent Current | 80–150µA (VCC), 50–100µA (VBS) - enables low-power standby modes in battery-powered tools |
| Operating Temperature | –40°C to +125°C - qualified for industrial motor drives and automotive cabin electronics |
Pinout & Package
Package: W-DFN3030-10 (Type TH), 3.0mm × 3.0mm × 0.75mm, matte tin terminals, moisture sensitivity level 3, 0.017g weight.
| 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 ≥1µF ceramic |
| 2 NC | No internal connection | Must remain unconnected; no PCB trace or via allowed |
| 3 VB | High-side floating supply | Connects to bootstrap capacitor anode; rated up to +120V absolute max |
| 4 HO | High-side gate drive output | Drives N-MOSFET gate referenced to VS; requires RC snubber if driving >100pF loads |
| 5 VS | High-side floating return | Switching node reference for HO; must be routed with minimal inductance to MOSFET source |
| 6 EN | Enable logic input | Active-high; pulls HO/LO low when logic low; supports system-level fault shutdown |
| 7 HIN | High-side input control | In-phase with HO; accepts 3.3V/5V logic; includes 0.7V hysteresis for noise immunity |
| 8 LIN | Low-side input control | In-phase with LO; synchronous with HIN but independently controllable for asymmetric PWM |
| 9 COM | Low-side and logic ground return | Common return for VCC, LO, and logic; must connect to PCB ground plane under package |
| 10 LO | Low-side gate drive output | Drives N-MOSFET gate referenced to COM; 2.5A sink ensures fast turn-off of high-Ciss devices |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | Eliminates external diode (VF = 0.6–1.75 V), reducing BOM count and layout area by ~15% in half-bridge designs |
| Dual UVLO protection | Independent monitoring of VCC and VB supplies prevents partial drive conditions that cause MOSFET overheating or shoot-through |
| Cross-conduction prevention | Hardware-enforced dead-time logic ensures HO and LO never activate simultaneously, even during rapid input transitions |
| Ultra-low standby current | <1µA shutdown current (ICCSD) enables multi-year battery life in portable power tools with enable-controlled sleep mode |
| Matched propagation delays | ≤10ns HO/LO delay mismatch allows use in ZVS/ZCS topologies without additional timing compensation circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-frequency half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2005STRPBF | Higher VBS UVLO (6.5V min), no integrated bootstrap diode, SOIC-16 package | Requires external bootstrap diode and larger PCB area; better suited for 100–200V industrial inverters | Select when higher bootstrap supply robustness is required and board space permits SOIC footprint |
| LM5109BMAX/NOPB | Separate high-side/low-side enable pins, 1A/1.5A drive, MSOP-8 package | Lacks cross-conduction logic; requires external dead-time control; lower drive strength limits switching frequency | Choose for cost-sensitive, lower-power (<50W) applications where timing margin allows external dead-time generation |
Compared with IRS2005STRPBF and LM5109BMAX/NOPB, the DGD0579UFN-7 delivers superior integration (bootstrap diode + matched delays), smaller footprint (W-DFN3030-10), and tighter timing control-making it optimal for space-constrained, high-frequency (>500kHz) consumer and industrial power stages.

FAQ
What is the maximum allowable dVS/dt for reliable high-side operation?
The DGD0579UFN-7 specifies a maximum dVS/dt rating of 50 V/ns under recommended operating conditions. This value is validated per the datasheet's Absolute Maximum Ratings table and ensures immunity to false triggering during fast-switching events in hard-switched half-bridges. Exceeding this rate may cause unintended HO turn-on due to capacitive coupling through the level-shifter.
Can the EN pin be left unconnected for always-on operation?
No. The EN pin must be actively driven high (≥1.6V) for normal operation; leaving it floating risks undefined behavior due to internal leakage paths. For always-on use, tie EN directly to VCC via a 10kΩ pull-up resistor. The datasheet specifies VEIH = 1.6V min and VEIL = 0.5V max, confirming strict logic-level requirements.
Is the internal bootstrap diode rated for continuous 100mA forward current?
The internal bootstrap diode is characterized for VF = 1.4–1.75V at IF = 100mA (DC), but its safe operating area depends on duty cycle and thermal design. At 100% duty, average current must stay below 10mA to avoid junction overheating; pulsed operation (e.g., 50% duty at 500kHz) supports higher peak currents. Derating is required above +85°C ambient.
Does the DGD0579UFN-7 support independent control of high-side and low-side outputs?
Yes. HIN and LIN are fully independent logic inputs, allowing asymmetric PWM, three-state control (via EN), and custom dead-time insertion in MCU firmware. The cross-conduction prevention logic only blocks simultaneous HO/LO high states-it does not force synchronization or override individual input states.
