Product details
Overview
DGD0280WTQ from Diodes Incorporated is an automotive-grade low-side single-channel gate driver IC with integrated 3.3V LDO regulator, designed to drive MOSFETs and IGBTs in high-speed switching applications. It delivers 2.5A source / 2.8A sink peak output current, operates from 4.5V to 18V supply, features 35ns typical propagation delay, and supports logic inputs down to 3.3V for direct MCU interfacing in motor control and DC-DC converters.
For engineers reviewing the DGD0280WTQ datasheet, DGD0280WTQ pinout, DGD0280WTQ application, or DGD0280WTQ equivalent, key selection criteria include its AEC-Q100 qualification, TSOT25 package thermal performance (RθJA = 117°C/W), 3.3V ±1% LDO accuracy at +25°C, undervoltage lockout thresholds (4.5V/4.2V), and fast rise/fall times (20ns/15ns) enabling compact power-stage designs.
Technical Context
The DGD0280WTQ implements a non-inverting low-side driver architecture with internal UVLO monitoring of VCC and thermal shutdown at 150°C turn-on / 125°C turn-off. Its logic input accepts TTL/CMOS levels (VIH ≥ 2.0V, VIL ≤ 0.8V) and exhibits 0.5V hysteresis for noise immunity.
The integrated LDO supplies regulated 3.3V ±1% at up to 15mA load, with line regulation of 21–38mV over 5–18V input and load regulation ≤10mV across 0.1–10mA. Propagation delays are tightly matched (tON/tOFF typ 35ns/30ns), supporting >10MHz switching in SMPS and motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Drive Current | 2.5A source / 2.8A sink - sufficient to rapidly charge/discharge gate capacitance of medium-power MOSFETs/IGBTs |
| Propagation Delay | 35ns typical - enables high-frequency PWM operation up to ~10MHz without timing skew issues |
| LDO Output | 3.3V ±1% at +25°C, 15mA max - powers external logic or sensors without external regulator |

| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| UVLO Thresholds | VCCUV+ = 4.75V, VCCUV− = 4.5V - prevents erratic gate drive during brown-out conditions |
| Rise/Fall Time | 20ns / 15ns typical (CL = 1000pF) - minimizes switching losses in hard-switched topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side gate driver with LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXDI602SI | Higher 6A peak drive, no integrated LDO, SOIC-8 package | Requires external 3.3V regulator; better suited for high-current discrete FETs | Select when gate charge exceeds 20nC and board space allows SOIC-8 |
| TPS28225DR | 2A peak drive, no LDO, 4.5–14V VCC range, 20ns propagation delay | Lower drive strength and narrower supply range; optimized for cost-sensitive industrial SMPS | Select when LDO not required and ambient temperature stays below +105°C |
Compared with IXDI602SI and TPS28225DR, the DGD0280WTQ uniquely combines AEC-Q100 qualification, integrated 3.3V LDO, and TSOT25 footprint-making it optimal for space-constrained automotive power stages where supply rail consolidation and functional safety compliance are critical.

FAQ
What is the maximum capacitive load the DGD0280WTQ can drive reliably?
The DGD0280WTQ is characterized with CL = 1000pF for timing parameters (tr, tf, tON, tOFF). Its 2.8A sink capability supports gate charges up to ~28nC at 100ns switching times. For loads exceeding 2000pF, layout parasitics and PCB trace inductance must be minimized to avoid ringing or shoot-through risk.
Does the 3.3V LDO require an external capacitor?
Yes - a minimum 1µF ceramic capacitor (X5R/X7R) must be placed between the 3V3 pin and COM, located within 2mm of the device. This stabilizes regulation and suppresses high-frequency noise; larger values (2.2–4.7µF) improve transient response under pulsed 15mA loads.
Can the DGD0280WTQ drive a high-side N-channel MOSFET directly?
No - the DGD0280WTQ is a dedicated low-side driver with ground-referenced output stage. It lacks bootstrap or floating supply capability required for high-side N-MOSFET drive. Use a dedicated high-side or half-bridge driver (e.g., DGD0502) for such configurations.
Is the thermal shutdown feature latched or auto-recovering?
The thermal shutdown is auto-recovering: it disables the output when junction temperature reaches 150°C (TSDON), then re-enables after cooling to 125°C (TSDOFF), providing 25°C hysteresis. No external reset or power cycle is needed, enabling fault-tolerant operation in intermittent overload scenarios.
