Product details
Overview
DGD0216WT-7 from Diodes Incorporated is a non-inverting, low-side MOSFET/IGBT gate driver IC in TSOT25 package, delivering 1.9A peak source / 1.8A sink output current, 35ns typical propagation delay, and 15ns typical rise/fall times at 12V supply. It operates from 4.5V to 18V, accepts 3.3V logic inputs, and supports DC-DC converters and motor control systems requiring fast, noise-immune switching.
For engineers reviewing the DGD0216WT-7 datasheet, DGD0216WT-7 pinout, DGD0216WT-7 application, or DGD0216WT-7 equivalent, key selection criteria include its non-inverting logic configuration, ±5V ground pin tolerance, 500mA reverse output current immunity, -40°C to +125°C operating range, and TSOT25 thermal performance (RθJA = 188°C/W).
Technical Context
The DGD0216WT-7 implements a dual-MOSFET output stage with internal P-channel (high-side) and N-channel (low-side) drivers, enabling rail-to-rail gate drive capability. Its input stage accepts TTL/CMOS-compatible signals down to 3.3V and features matched propagation delays between IN and OUT pins for precise timing control in high-frequency power stages.
Designed for low-side switching only, it lacks bootstrap or level-shifting circuitry and requires a common ground reference between VCC, COM, and the driven MOSFET's source. Its robustness against ground bounce (±5V on COM) and reverse current (500mA into outputs) ensures reliable operation in noisy industrial power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5V to 18V - Enables direct use with 5V, 12V, and 15V intermediate bus rails without LDO pre-regulation. |
| Peak Output Current | 1.9A source / 1.8A sink - Drives large gate capacitances (e.g., >3nF) at high dV/dt without external buffers. |
| Propagation Delay | 35ns typ (tON/tOFF) - Supports PWM frequencies up to ~10MHz in critical timing paths like PFC controllers. |
| Rise/Fall Time | 15ns typ (CL = 1000pF, VCC = 12V) - Minimizes switching losses in hard-switched topologies such as boost and half-bridge LLC. |
| Logic Input Compatibility | 3.3V–5V CMOS/TTL - Interfaces directly with modern MCUs, DSPs, and digital controllers without level shifters. |
| Operating Temperature | -40°C to +125°C - Qualified for under-hood automotive and industrial ambient conditions without derating. |
| Ground Pin Tolerance | ±5V on COM pin - Survives ground bounce transients in high-current PCB layouts without latch-up or damage. |
Pinout & Package
Package: TSOT25 (5-pin, 2.9mm × 2.8mm × 1.1mm), lead-free, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN*) | Inverted logic input | Unused in DGD0216 configuration; must be left open or tied to VCC/COM to avoid floating node noise coupling. |
| 2 (COM) | Power ground return | Low-inductance return path for both supply and output current; requires dedicated ground plane connection. |
| 3 (IN) | Non-inverting logic input | Directly drives OUT in phase; accepts 0–5V logic; 2.4V VIH threshold ensures noise margin with 3.3V MCU outputs. |
| 4 (OUT) | Gate drive output | Push-pull output capable of sourcing 1.9A and sinking 1.8A; connects directly to MOSFET gate via series resistor. |
| 5 (VCC) | Positive supply input | Accepts 4.5–18V; requires local 100nF ceramic decoupling placed ≤2mm from pin to suppress switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| Non-inverting logic architecture | IN → OUT direct mapping simplifies control logic in synchronous rectifiers and half-bridge low-side drivers. |
| ±5V ground pin tolerance | Eliminates need for isolated ground references in high-dI/dt PCB layouts, reducing EMI filter complexity. |

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 (IXYS) | Higher 4A peak output, SOIC-8 package, no ±5V COM tolerance, 45ns propagation delay. | Preferred for higher-power (>5kW) industrial inverters requiring greater drive strength and thermal mass. | Select when >2A gate current or SOIC thermal margin is required; avoid if board space or ground bounce immunity is constrained. |
| TC4427ACOA (Microchip) | 1.2A peak output, SOIC-8, 30ns propagation delay, no reverse current rating, 5V-only supply. | Suitable for cost-sensitive 5V-only consumer power supplies with moderate switching speed needs. | Choose for legacy 5V designs with lower gate charge loads; not recommended for 12V+ buses or noisy industrial grounds. |
Compared with IXDN404PI and TC4427ACOA, the DGD0216WT-7 uniquely balances high peak current (1.9A), ultra-fast timing (35ns), ±5V ground resilience, and compact TSOT25 packaging-making it optimal for space-constrained, high-reliability 4.5–18V power stages where ground integrity and thermal efficiency are prioritized over raw current headroom.

FAQ
What is the logic configuration of DGD0216WT-7?
The DGD0216WT-7 features a non-inverting logic configuration: a high-level signal on the IN pin produces a high-level output on the OUT pin. The IN* pin is inverted and unused in this variant; it must be left open or tied to VCC/COM to prevent noise coupling. This differs from the DGD0215WT-7, which provides inverted output.
Can DGD0216WT-7 drive high-side MOSFETs?
No. The DGD0216WT-7 is a dedicated low-side gate driver with a grounded COM pin and no bootstrap or level-shifting circuitry. It cannot float above ground potential and therefore cannot drive high-side N-channel MOSFETs. For high-side drive, a dedicated high-side or half-bridge driver (e.g., DGD0506) is required.
What is the maximum safe operating voltage on the COM pin?
The COM pin tolerates -5V to +5V relative to system ground while maintaining functionality and avoiding damage-verified per absolute maximum ratings. This ±5V specification allows operation despite ground bounce transients up to 5V peak in high-dI/dt PCB layouts, eliminating need for separate ground isolation.
Does DGD0216WT-7 require an external gate resistor?
Yes-a series gate resistor (typically 2.2Ω–10Ω) is required between OUT and the MOSFET gate to dampen ringing, limit peak current, and control slew rate. The resistor value must be selected based on MOSFET Qg, desired switching speed, and EMI constraints; omitting it risks oscillation and device overstress.
