Product details
Overview
DGD0280WT-7 from Diodes Incorporated is a low-side single-channel gate driver IC with integrated 3.3V LDO regulator, designed to drive MOSFETs and IGBTs in power-switching circuits. It delivers 2.5A source / 2.8A sink peak output current, supports 4.5V–18V VCC supply, features 35ns typical propagation delay, and operates across –40°C to +125°C in a TSOT25 package.
For engineers reviewing the DGD0280WT-7 datasheet, DGD0280WT-7 pinout, DGD0280WT-7 application, or DGD0280WT-7 equivalent, key selection criteria include LDO accuracy (±1% at 3.3V/15mA), UVLO thresholds (4.5V turn-on, 4.2V turn-off), logic-level compatibility down to 3.3V, and fast switching performance for DC-DC converters and motor control designs.
Technical Context
The DGD0280WT-7 integrates a non-inverting low-side driver stage with internal undervoltage lockout and a precision 3.3V LDO regulator delivering up to 15mA. Its input accepts TTL/CMOS logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V) and exhibits 0.5V input hysteresis for noise immunity.
AC timing is optimized for high-frequency operation: 20ns typical rise time, 15ns typical fall time, and matched 35ns typical propagation delays for both turn-on and turn-off paths - enabling clean, low-jitter gate control in SMPS and motor drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5V to 18V - supports wide-input industrial and automotive power rails |
| Output Current | 2.5A source / 2.8A sink - drives medium-power MOSFETs/IGBTs without external boost |
| LDO Output | 3.3V ±1% @ 10mA - powers MCU peripherals or level-shifting circuitry with tight regulation |
| Propagation Delay | 35ns typ - enables >10MHz switching frequency with minimal timing skew |
| Rise/Fall Time | 20ns / 15ns typ (CL = 1000pF) - reduces switching losses and EMI in compact layouts |
| UVLO Threshold | 4.75V (rising), 4.5V (falling) - prevents erratic gate drive during brown-out conditions |
| Operating Temp | –40°C to +125°C - qualified for under-hood and industrial ambient environments |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Positive supply input | Primary power rail for driver core and LDO; requires local 1µF ceramic decoupling |
| 2 COM | Ground reference | Common return path for VCC, LDO, and output stage; must be low-inductance connection |
| 3 IN | Logic input | Non-inverting TTL/CMOS-compatible signal; 3.3V–5V tolerant with 0.5V hysteresis |
| 4 3V3 | LDO regulated output | Stable 3.3V supply for auxiliary circuitry; max 15mA load with <38mV line/load regulation |
| 5 OUT | Gate drive output | Low-side N-channel driver output; 2.8A sink capability enables fast MOSFET turn-off |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 3.3V LDO | Eliminates need for external regulator; ±1% accuracy ensures reliable MCU interface voltage |
| Fast matched propagation delays | 35ns typical tON/tOFF matching minimizes shoot-through risk in half-bridge configurations |
| Logic-level compatible input | Accepts 3.3V logic directly - no level shifter required when interfacing with modern MCUs |
| Undervoltage lockout | Prevents partial turn-on of power devices during supply ramp-up or brown-out events |
| Extended temperature range | Rated for full performance from –40°C to +125°C junction - suitable for under-hood and industrial use |
Applications
| DC-DC Converters | Motor Controls |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side gate driver with integrated LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXDI602SI | No integrated LDO; 6A peak drive; SOIC-8 package | Requires external 3.3V regulator; better suited for higher-current discrete MOSFETs | Select when higher drive strength is needed and board space allows SOIC-8 and external LDO |
| TPS28225DR | 3.3V LDO not integrated; dual-channel; 4A peak; 12V VCC max | Lacks on-chip regulation; limited supply range excludes 15V/18V systems | Choose for dual-driver needs where system already provides clean 3.3V rail and VCC ≤12V |
Compared with IXDI602SI and TPS28225DR, the DGD0280WT-7 uniquely combines space-saving TSOT25 packaging, integrated ±1% 3.3V LDO, and full 4.5V–18V operation - reducing BOM count and PCB area in cost-sensitive, thermally constrained low-to-medium power applications.

FAQ
What is the maximum capacitive load the DGD0280WT-7 can drive reliably?
The DGD0280WT-7 is characterized with CL = 1000pF for timing specifications, and its 2.8A sink capability supports gate charges up to ~25nC at 35ns rise time. For larger MOSFETs (e.g., Qg > 30nC), external gate resistors may be needed to manage EMI and overshoot - but the driver remains functional up to 50nC loads with appropriate layout and decoupling.
Does the integrated LDO regulate under varying VCC conditions?
Yes - the LDO maintains 3.3V output within ±1% at 10mA load across the full 5V–18V VCC range, with line regulation specified at ≤38mV. Load regulation is ≤10mV from 0.1mA to 10mA, ensuring stable MCU I/O or sensor biasing even during wide-input transients.
Can the DGD0280WT-7 be used in high-side configuration?
No - the DGD0280WT-7 is strictly a low-side driver with ground-referenced output (OUT pin sinks to COM). It lacks high-side level-shifting or bootstrap circuitry. For high-side driving, Diodes offers complementary parts like the DGD0502 or dedicated high-side drivers such as the ZXGD3003.
Is the DGD0280WT-7 AEC-Q100 qualified?
No - the DGD0280WT-7 is not AEC-Q100 qualified per the datasheet. Diodes states that automotive-grade versions require specific change control and PPAP capability; this part is intended for industrial and commercial applications. For automotive use, contact Diodes directly for qualified alternatives such as the AP2204K or AUIRS2181S.
