Product details
Overview
DGD0215WT-7 from Diodes Incorporated is a high-speed, low-side MOSFET/IGBT gate driver IC with inverting logic configuration, delivering 1.9A peak source / 1.8A sink output current, 35ns typical propagation delay, and operation across 4.5V–18V supply voltage - used to drive power switches in DC-DC converters and PFC circuits.
For engineers reviewing the DGD0215WT-7 datasheet, DGD0215WT-7 pinout, DGD0215WT-7 application, or DGD0215WT-7 equivalent, key selection criteria include its TSOT25 package, inverted input/output behavior, -40°C to +125°C operating range, noise immunity (±5V ground tolerance), and reverse-current survivability (500mA into outputs).
Technical Context
The DGD0215WT-7 implements a dual-MOSFET output stage (P-channel high-side + N-channel low-side) with matched turn-on/turn-off timing, enabling clean switching of external power devices. Its logic inputs (IN and IN*) accept TTL/CMOS levels down to 3.3V and support open-circuit handling for flexible control interface.
Designed for low-inductance gate-drive loops, it requires tight PCB layout between VCC decoupling capacitors, gate resistor, and MOSFET gate-source path. The device sustains ±5V transient on COM pin and 500mA reverse current on OUT without functional disruption or latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5V to 18V - supports wide-input industrial and automotive power rails without external regulation. |
| Peak Output Current | 1.9A source / 1.8A sink - drives high-Qg MOSFETs at high frequency with minimal gate resistance. |
| Propagation Delay | 35ns typical - enables >10 MHz switching in resonant topologies with precise timing control. |
| Rise/Fall Time | 15ns typical (CL = 1000pF) - reduces switching losses and EMI in fast-switching SMPS stages. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood and industrial ambient environments without derating. |
| Logic Input Compatibility | TTL/CMOS down to 3.3V - interfaces directly with modern MCUs and digital controllers without level-shifting. |
| Ground Pin Tolerance | ±5V transient immunity - withstands ground bounce in noisy power systems without damage or logic upset. |
Pinout & Package
Package: TSOT25 (5-pin, 2.9mm × 2.8mm × 1.0mm, matte tin-plated leads, RoHS-compliant "Green" molding compound, MSL Level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN*) | Inverting logic input | Drives OUT* in phase; use for complementary control or leave open if unused. |
| 2 (COM) | Power ground return | Reference for VCC and output stage; tolerant of ±5V transients relative to system ground. |
| 3 (IN) | Non-inverting logic input | Drives OUT out of phase with IN*; primary control signal for inverted-output configuration. |
| 4 (OUT*/OUT) | Gate drive output | Delivers 1.9A/1.8A pulsed current to MOSFET/IGBT gate; rated for 0V to VCC+0.3V swing. |
| 5 (VCC) | Positive supply input | Accepts 4.5V–18V; requires local 100nF ceramic decoupling placed within 2mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Inverting output logic | IN → OUT* (180° phase shift) enables direct replacement in legacy inverter-driven half-bridge gate control paths. |
| Matched propagation delays | 35ns tON/tOFF typ ensures <1ns skew between rising/falling edges - critical for minimizing shoot-through risk. |
| Reverse current survivability | Withstands 500mA forced into OUT pin without latch-up or logic corruption - protects against Miller-induced gate discharge events. |
| Noise-immune ground architecture | ±5V tolerance on COM pin prevents false triggering during ground bounce in high-dI/dt power stages. |
| Extended temperature operation | Full 1.9A drive capability maintained from -40°C to +125°C - eliminates need for thermal derating in sealed enclosures. |
Applications
| DC-DC Converters | PFC Circuits |
|---|---|
Use Scenario: High-efficiency synchronous buck converter operating at 500kHz–2MHz with GaN or SiC MOSFETs. IC Role / Device Role / Timing Role: Low-side gate driver providing fast, high-current turn-on/turn-off control to minimize conduction and switching losses.

IC Role / Device Role / Timing Role: Drives low-side switch in continuous conduction mode (CCM) PFC with precise zero-crossing synchronization. Use Value: Matched 35ns propagation delays ensure consistent dead-time margin across temperature, preventing shoot-through at line peaks. |
| Motor Control Drivers | Industrial SMPS |
Use Scenario: Three-phase inverter stage in BLDC motor drives for HVAC compressors and pumps. IC Role / Device Role / Timing Role: Controls low-side IGBTs in each leg with TTL-compatible input from MCU PWM timers. Use Value: 3.3V logic compatibility eliminates level-shifters; ±5V COM tolerance maintains reliability amid motor back-EMF transients. | Use Scenario: 1kW telecom rectifier with interleaved LLC resonant topology requiring robust gate drive under load transients. IC Role / Device Role / Timing Role: Drives parallel low-side MOSFETs in synchronous rectification stage with high peak current demand.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXDN404PI | 4A peak output, SOIC-8 package, no IN* pin - single-input only. | Higher drive strength but larger footprint; lacks dual-input flexibility for complementary control. | Select when >1.9A drive is required and board space allows SOIC-8; not drop-in due to pin count and logic architecture. |
| TC4427ACOA | 1.2A peak, SOIC-8, non-inverting only, 60ns propagation delay. | Lower current and slower timing; suitable for lower-frequency (<500kHz), lower-power applications. | Choose for cost-sensitive, low-speed designs where 1.2A drive suffices and inverted logic is unnecessary. |
Compared with IXDN404PI and TC4427ACOA, the DGD0215WT-7 uniquely balances 1.9A drive, 35ns speed, TSOT25 compactness, and inverting logic - making it optimal for space-constrained, high-frequency PFC and DC-DC converters requiring precise edge control.

FAQ
What is the logic configuration of DGD0215WT-7?
The DGD0215WT-7 features an inverting logic configuration: a high-level signal on the IN pin produces a low-level output on OUT*, while a high-level signal on IN* produces a high-level output on OUT*. This dual-input structure allows flexible control of complementary gate signals without external inverters.
Can DGD0215WT-7 drive both MOSFETs and IGBTs?
Yes - the DGD0215WT-7 is explicitly characterized to drive both N-channel MOSFETs and NPT IGBTs, with 1.9A peak source and 1.8A sink current sufficient for gate charges up to 60nC at 1MHz switching. Its 4.5V–18V VCC range accommodates IGBT gate thresholds and MOSFET enhancement requirements.
Is DGD0215WT-7 pin-compatible with DGD0216WT-7?
No - although both share identical TSOT25 packaging and pinout, the DGD0215WT-7 provides inverted output logic (IN → OUT*), whereas DGD0216WT-7 provides non-inverting logic (IN → OUT). Swapping them requires corresponding firmware or schematic changes to maintain correct switching polarity.
What layout practices are critical for DGD0215WT-7 stability?
A low-inductance gate loop is essential: place 100nF ceramic decoupling capacitor ≤2mm from VCC/COM pins, route OUT directly to MOSFET gate with minimal trace length, and keep gate resistor (Rg) adjacent to the driver. Avoid shared ground paths between power and logic sections to prevent COM pin noise coupling.
