Product details
Overview
DGD0211CWTQ from Diodes Incorporated is a single-channel, low-side gate driver IC designed to drive MOSFETs and IGBTs in high-frequency power stages. It delivers 1.9A source / 1.8A sink peak output current, features dual logic inputs (IN and IN*) supporting TTL/CMOS levels down to 3.3V, and achieves 35ns typical propagation delay with 15ns typical rise/fall times. It operates from 4.5V to 18V supply voltage across –40°C to +125°C and is AEC-Q100 qualified for automotive power conversion.
For engineers reviewing the DGD0211CWTQ datasheet, DGD0211CWTQ pinout, DGD0211CWTQ application, or DGD0211CWTQ equivalent, key selection criteria include its TSOT25 footprint compatibility, dual-input logic configuration, fast switching performance under 1000pF load, automotive qualification status, and thermal resistance of 188°C/W on standard FR-4.
Technical Context
The DGD0211CWTQ implements a non-inverting/inverting dual-input logic interface driving a single low-side N-channel output stage. Its internal architecture supports simultaneous enable/disable control via complementary input states, with defined output behavior per the Input/Output Response Table (e.g., IN=1/IN*=0 → OUT=1; IN=0/IN*=1 → OUT=0).
It operates as a fixed-supply, single-output gate driver without bootstrap or level-shifting circuitry. All timing parameters-including tON/tOFF (35ns typ), tr/tf (15ns typ)-are specified at VCC = 12V, CL = 1000pF, and TA = +25°C, and remain valid across its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 1.9A source / 1.8A sink - drives gate capacitance of medium-power MOSFETs/IGBTs in SMPS and motor control stages |
| Propagation Delay | 35ns typical - enables stable operation up to ~10 MHz switching frequency in hard-switched topologies |
| Rise/Fall Time | 15ns typical (CL = 1000pF) - minimizes switching losses during turn-on/turn-off transitions |
| Supply Voltage Range | 4.5V to 18V - compatible with 5V, 12V, and 15V intermediate bus rails in industrial and automotive systems |
| Logic Input Threshold | VIH ≥ 2.4V, VIL ≤ 0.8V - ensures robust interfacing with 3.3V and 5V MCUs without level shifters |
| Operating Temperature | –40°C to +125°C - supports under-hood automotive environments and high-ambient industrial converters |
| Thermal Resistance | RθJA = 188°C/W - requires minimal PCB copper area for thermal management in TSOT25 package |
Pinout & Package
Package: TSOT25 - 5-pin, ultra-thin, surface-mount plastic package with 0.95mm height, 2.90mm × 2.80mm body, and 0.95mm lead pitch. Matte tin-plated leads, moisture sensitivity level 1, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Positive supply input | Connects to main gate drive rail (4.5–18V); decoupling capacitor required near pin |
| 2 - COM | Power ground return | Low-inductance return path for output current; must tie directly to power ground plane |
| 3 - IN | Non-inverting logic input | Active-high control: logic high enables high-side output state when IN* is low |
| 4 - IN* | Inverting logic input | Active-low control: logic low enables high-side output state when IN is high |
| 5 - OUT | Gate drive output | Push-pull output stage driving MOSFET/IGBT gate; referenced to COM |
Key Features
| Feature | Design Value |
|---|---|
| Dual logic input configuration | Independent IN (non-inverting) and IN* (inverting) pins allow flexible control logic mapping without external inverters |
| Fast switching performance | 35ns propagation delay and 15ns edge times reduce dead-time uncertainty and improve efficiency in high-frequency converters |
| Automotive qualification | AEC-Q100 Grade 1 qualified, PPAP capable, manufactured in IATF 16949 certified facilities - suitable for safety-critical power stages |
| Wide supply voltage range | 4.5V–18V operation supports direct connection to common intermediate bus voltages without regulation |
| Low quiescent current | 100µA max ICCQ at 25°C - reduces standby power loss in always-on automotive subsystems |

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 |
|---|---|---|---|
| IXDI602PI | Higher peak current (6A), TO-220 package, no dual-input logic | Targeted at higher-power discrete gate driving; lacks automotive qualification | Choose for >3A gate drive needs where board space and qualification are secondary |
| TPD12S521DBTR | Integrated ESD protection, 1.2A output, 3.3V-only supply, no IN* pin | Designed for USB/DisplayPort interface protection-not a gate driver replacement | Not functionally equivalent; avoid for power switching applications |
Compared with IXDI602PI and TPD12S521DBTR, the DGD0211CWTQ uniquely balances automotive qualification, dual-input flexibility, and compact TSOT25 packaging-making it optimal for space-constrained, high-reliability low-side drive in 12V–48V systems.

FAQ
Is DGD0211CWTQ pin-compatible with other Diodes gate drivers like DGD0212?
No. DGD0211CWTQ has five pins in TSOT25 with dedicated IN/IN* inputs and single OUT, while DGD0212 is a dual-channel driver in SO-8. Pin count, pinout, and channel count differ fundamentally-no mechanical or electrical pin compatibility exists between them.
Can DGD0211CWTQ drive high-side MOSFETs directly?
No. DGD0211CWTQ is a low-side driver only: its OUT pin is referenced to COM (power ground), not floating. Driving high-side N-MOSFETs requires level-shifting or bootstrap circuitry not integrated in this device.
What is the maximum capacitive load this driver can switch reliably?
Based on AC characterization at CL = 1000pF, the driver maintains 15ns rise/fall times and 35ns propagation delay. For loads exceeding 2000pF, edge speed degrades significantly; use external gate resistors and verify timing margins in final layout.
Does DGD0211CWTQ require external pull-up or pull-down resistors on IN/IN*?
No. The inputs have defined VIH/VIL thresholds and low bias currents (<5µA). However, if left unconnected, IN and IN* must be tied to VCC or COM to prevent floating states that could cause undefined output behavior per the Input/Output Response Table.
