Product details
Overview
DGD2104AS8-13 from Diodes Incorporated is a high-speed, high-voltage half-bridge gate driver IC designed to control two N-channel MOSFETs or IGBTs in bootstrap-configured power stages. It features 600V high-side floating capability, 210mA source / 360mA sink output current, and a fixed 520ns internal deadtime-enabling robust operation in DC-DC converters and motor control inverters.
For engineers reviewing the DGD2104AS8-13 datasheet, DGD2104AS8-13 pinout, DGD2104AS8-13 application, or DGD2104AS8-13 equivalent, key selection criteria include bootstrap-compatible high-side voltage rating, TTL/CMOS logic compatibility down to 3.3V, negative transient-tolerant outputs, undervoltage lockout on VCC, and SO-8 (Type TH) thermal performance up to +125°C.
Technical Context
The DGD2104AS8-13 integrates independent high-side and low-side drivers with matched propagation delays (tON ≤ 820ns, tOFF ≤ 220ns) and tight delay matching (≤60ns), minimizing shoot-through risk in hard-switching topologies. Its Schmitt-triggered inputs ensure noise immunity across wide common-mode voltage swings (VS = –5V to +600V).
Internal UVLO thresholds (VCCUV+ = 8.0–9.8V, VCCUV– = 7.4–9.0V) protect against erratic switching during supply brownouts, while the 520ns deadtime is fixed-not programmable-and applies to both LO→HO and HO→LO transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 600V max VB–VS offset - enables use in 400V DC bus systems with margin |
| Output Drive Strength | 210mA source / 360mA sink - sufficient for fast turn-on/turn-off of 10nC–30nC gate charges |
| Internal Dead Time | 520ns typical - prevents cross-conduction without external timing circuitry |
| Logic Input Compatibility | 3.3V–5V TTL/CMOS - interfaces directly with microcontrollers and PWM controllers |
| Operating Temperature | –40°C to +125°C - supports industrial and automotive under-hood environments |
| VCC Supply Range | 10V to 20V - accommodates regulated 12V or 15V gate drive rails |
| Propagation Delay Match | ≤60ns HO/LO delay mismatch - ensures symmetrical switching timing critical for ZVS/ZCS topologies |
Pinout & Package
Supplied in an SO-8 (Type TH) package with standard JEDEC 2-layer FR-4 thermal resistance (RθJA = 200°C/W), matte tin-plated leads, and moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Logic and low-side supply input | Provides power for internal logic and low-side driver; requires 10–20V decoupled supply |
| 2 IN | In-phase logic input | Drives both HO and LO outputs simultaneously when SD* is high; TTL/CMOS compatible |
| 3 SD* | Active-low shutdown input | Pulls both outputs low when asserted; enables system-level fault protection |
| 4 COM | Low-side return and logic ground | Common reference for VCC, IN, SD*, and LO; must be connected to low-side source |
| 5 LO | Low-side gate drive output | Directly drives low-side MOSFET gate; rated for 360mA sink, tolerant to negative transients |
| 6 VS | High-side floating supply return | Reference node for high-side driver; tracks high-side source voltage in bootstrap operation |
| 7 HO | High-side gate drive output | Drives high-side MOSFET gate referenced to VS; 210mA source capability, 600V-rated |
| 8 VB | High-side floating supply input | Connects to bootstrap capacitor positive terminal; supplies high-side driver stage |
Key Features
| Feature | Design Value |
|---|---|
| Floating high-side driver | Operates with VB–VS up to 600V in bootstrap mode - eliminates need for isolated supplies |
| Negative transient tolerance | Outputs withstand –5V undershoot at COM/VS - improves reliability in noisy power stage layouts |
| Schmitt-triggered inputs | Hysteresis ≥1.7V (VIH–VIL) - rejects noise on IN/SD* lines in EMI-prone environments |
| VCC undervoltage lockout | Asymmetric thresholds (8.2V rising, 7.4V falling) - prevents partial switching during brownout recovery |
| Thermal and environmental compliance | Lead-free, halogen-free, RoHS-compliant SO-8 package rated for –40°C to +125°C ambient |

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 650V VB–VS rating; 2.5A peak output; no integrated deadtime (external RC required) | Preferred where higher drive current or extended voltage margin is needed; requires external timing network | Select when driving >30nC gates or operating above 500V DC bus; accept added BOM complexity |
| UCC27211D | 600V rating; 4A source/sink; adjustable deadtime via external resistor; no SD* pin | Suited for high-frequency (>500kHz) resonant converters requiring tunable deadtime | Choose for designs needing >3A drive or fine deadtime tuning; omit if shutdown functionality is mandatory |
Compared with IRS21844SPbF and UCC27211D, the DGD2104AS8-13 offers integrated deadtime and active-low shutdown in a cost-optimized SO-8 footprint-ideal for mid-power industrial converters where simplicity and reliability outweigh ultra-high drive current needs.

FAQ
What is the maximum allowable dVS/dt for the DGD2104AS8-13?
The DGD2104AS8-13 specifies a maximum dVS/dt rating of 50 V/ns. This limit ensures reliable high-side level-shifting operation during fast switching transitions in hard-switched topologies. Exceeding this rate may cause false triggering or latch-up in the floating channel. Layout best practices-including short, low-inductance VS traces and proper bootstrap capacitor placement-are essential to stay within this specification.
Can the DGD2104AS8-13 drive IGBTs directly?
Yes-the DGD2104AS8-13 is explicitly qualified to drive N-channel IGBTs in half-bridge configurations. Its 360mA sink and 210mA source capability support typical IGBT gate charge requirements (Qg ≈ 20–50nC) at switching frequencies up to 100kHz. For higher Qg devices or >200kHz operation, external gate resistors or buffer stages may be needed to manage power dissipation and switching losses.
Is there a recommended minimum bootstrap capacitor value?
Diodes recommends a minimum 100nF ceramic bootstrap capacitor (X7R, 25V rating) placed close to pins VB and VS. This value ensures sufficient charge replenishment during continuous conduction at 50% duty cycle and 100kHz switching. Larger values (e.g., 220nF) improve margin under high-duty-cycle or high-frequency conditions but increase layout area and cost.
Why is the DGD2104AS8-13 marked "NOT RECOMMENDED FOR NEW DESIGN"?
This designation reflects Diodes' internal product lifecycle status: the DGD2104AS8-13 remains fully manufactured and supported, but newer alternatives (e.g., DGD2104M) offer enhanced features like improved ESD robustness or updated qualification. Aetrix Electronics continues to stock and support DGD2104AS8-13 for legacy design refreshes, repair, and cost-sensitive production where its specifications meet requirements.
