Product details
Overview
DGD2184S8-13 from Diodes Incorporated is a high-voltage, high-speed half-bridge gate driver IC designed to drive N-channel MOSFETs and IGBTs in switching power stages. It features 600V high-side bootstrap operation, 1.4A source / 1.8A sink output current, fixed 395ns internal deadtime, TTL/CMOS-compatible 3.3V logic inputs, and operates from –40°C to +125°C in SO-8 package. It is used in DC-DC converters and motor control inverters.
For engineers reviewing the DGD2184S8-13 datasheet, DGD2184S8-13 pinout, DGD2184S8-13 application, or DGD2184S8-13 equivalent, key selection criteria include high-side floating voltage capability (600V), output drive strength (1.4A/1.8A), internal deadtime (395ns), logic-level compatibility (3.3V), and thermal robustness (–40°C to +125°C).
Technical Context
The DGD2184S8-13 integrates independent high-side and low-side drivers with bootstrap-based high-side level shifting, enabling operation with VS up to 600V relative to COM. Its Schmitt-triggered IN and SD* inputs provide noise immunity, while undervoltage lockout (UVLO) thresholds of 8.2V (VCC) and 8.9V (VB) ensure safe turn-on sequencing.
It delivers matched propagation delays (tON typ 680ns, tOFF typ 270ns) and tight delay matching (≤90ns HO/LO turn-on skew), supporting high-frequency PWM control. The 395ns fixed deadtime prevents shoot-through in half-bridge topologies without external timing components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 600V max VS offset - enables use in 400V DC bus inverters and PFC stages |
| Output Drive Current | 1.4A source / 1.8A sink - sufficient to rapidly charge/discharge 10nF gate capacitance at >100kHz |
| Internal Deadtime | 395ns typ - hardware-enforced minimum off-time prevents cross-conduction in half-bridge |
| Logic Input Compatibility | 3.3V–20V tolerant - interfaces directly with microcontrollers, DSPs, and FPGA I/O without level shifters |
| Operating Temperature | –40°C to +125°C - supports under-hood automotive and industrial ambient conditions |
| Supply Voltage Range | VCC: 10V–20V; VB–VS: 10V–20V - accommodates wide input rail variations in SMPS designs |
| Propagation Delay Match | ≤90ns HO/LO turn-on skew - ensures symmetrical switching timing critical for low EMI |

| 8 (VB) | High-Side Bootstrap Supply | Provides floating bias for high-side driver; UVLO threshold 8.9V |
Key Features
| Feature | Design Value |
|---|---|
| Floating High-Side Driver | Supports 600V VS offset using bootstrap capacitor - eliminates need for isolated supplies in half-bridge |
| Integrated Deadtime | 395ns fixed hardware deadtime - removes external RC timing network and improves reliability |
| Negative Transient Tolerance | Outputs withstand –5V undershoot on VS and COM - improves robustness in noisy motor drive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844SPBF | Higher 2.5A peak output; no integrated deadtime (requires external RC) | Better suited for higher gate charge loads (>20nF); requires layout-sensitive timing network | Select when driving large IGBTs or needing higher peak current; accept added design complexity |
| DGD2184M | Same pinout and function; improved thermal resistance (RθJA = 160°C/W vs. 200°C/W) | Enables higher power density in thermally constrained layouts | Preferred for new designs per Diodes' notice; drop-in replacement with enhanced thermal performance |
Compared with IRS21844SPBF and DGD2184M, the DGD2184S8-13 offers integrated deadtime and simpler layout but lower peak drive current; DGD2184M provides identical functionality with better thermal margin, making it the recommended upgrade path.

FAQ
What is the maximum allowable dVS/dt for the DGD2184S8-13?
The DGD2184S8-13 specifies a maximum dVS/dt rating of 50 V/ns. This limit ensures reliable high-side level-shifting operation under fast-switching conditions typical in hard-switched converters. Exceeding this rate may cause false triggering or latch-up due to capacitive coupling into the VS node. Layout best practices-such as minimizing loop area and using local decoupling-must be followed to stay within this specification.
Does the DGD2184S8-13 require external bootstrap diode and capacitor?
Yes, the DGD2184S8-13 requires an external bootstrap diode and capacitor between VB and VS pins to generate the floating high-side supply. A fast recovery diode (e.g., 1N4148WS) and 0.1µF–1µF X7R ceramic capacitor are recommended. The bootstrap capacitor must be sized to maintain VB ≥ 8.9V under worst-case duty cycle and switching frequency to avoid UVLO-induced shutdown.
How does the shutdown (SD*) pin behave during fault conditions?
The SD* pin is active-low and asynchronous: asserting SD* immediately forces both HO and LO outputs low, overriding IN state and disabling gate drive regardless of input timing. It has Schmitt-trigger input with 2.5V rising threshold and 0.8V falling threshold, providing noise immunity. No internal pull-up exists-external pull-up to VCC is required for default-enable operation.
Is the DGD2184S8-13 pin-compatible with the DGD2184M?
Yes, the DGD2184S8-13 and DGD2184M share identical SO-8 pinout, electrical specifications, and functional behavior. The DGD2184M improves thermal resistance (RθJA = 160°C/W vs. 200°C/W) via enhanced package construction but requires no PCB or schematic changes. Diodes Incorporated explicitly recommends DGD2184M for new designs.
