Product details
Overview
DGD2104MS8-13 from Diodes Incorporated is a high-voltage half-bridge gate driver IC designed to control two N-channel MOSFETs or IGBTs in bootstrap-configured power stages. It delivers 290mA source / 600mA sink output current, supports high-side floating operation up to 600V, and operates across –40°C to +125°C. Used in DC-DC converters and motor controls where robust gate drive and noise immunity are critical.
For engineers reviewing the DGD2104MS8-13 datasheet, DGD2104MS8-13 pinout, DGD2104MS8-13 application, or DGD2104MS8-13 equivalent, key selection criteria include bootstrap high-side voltage rating (600V), integrated dead time (300–650 ns), TTL/CMOS-compatible 3.3V logic inputs, undervoltage lockout thresholds (VCCUV+ = 8.0–9.8V), and SO-8 thermal resistance (RθJA = 200°C/W).
Technical Context
The DGD2104MS8-13 implements independent high-side and low-side drivers with internal dead-time generation (300–650 ns) to prevent shoot-through. Its floating high-side section uses bootstrap biasing and tolerates dVS/dt transients up to 50 V/ns, enabling reliable operation in noisy motor-drive environments.
Logic inputs feature Schmitt-triggered thresholds (VIH ≥ 2.5V, VIL ≤ 0.8V at VCC = 10–20V) and dual undervoltage lockout circuits-separate for VCC (8.0–9.8V trip) and VB/VS (4.5–6.5V trip)-ensuring safe startup and fault recovery under brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 600V max VB–VS offset; enables use in 400V DC bus inverters and PFC stages. |
| Output Drive Strength | 290mA source / 600mA sink; sufficient to rapidly charge/discharge 10nF gate capacitance in <100ns. |
| Dead Time | 300–650 ns; hardware-enforced minimum off-time prevents cross-conduction in half-bridge switches. |
| Logic Input Compatibility | 3.3V–5V TTL/CMOS; interfaces directly with microcontrollers and PWM controllers without level-shifting. |
| Operating Temperature | –40°C to +125°C ambient; qualified for industrial and automotive under-hood motor-control applications. |
| Propagation Delay | tON = 680–820 ns (VS = 0V), tOFF = 150–220 ns (VS = 600V); ensures precise timing alignment in high-frequency switching. |
| Undervoltage Lockout | VCCUV+ = 8.0–9.8V, VBSUV+ = 4.5–6.5V; prevents erratic output behavior during supply ramp-up or sag. |
Pinout & Package
Supplied in standard SO-8 (Small Outline-8) package with matte tin-plated leads, JEDEC MS-012AC compliant, moisture sensitivity level 3, and 0.074g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Low-side and logic supply input | Accepts 10–20V; powers internal logic, level shifters, and low-side driver stage. |
| 2 IN | In-phase logic input | Drives both HO and LO outputs synchronously; Schmitt-triggered for noise immunity. |
| 3 SD* | Active-low shutdown input | Pulls both outputs low when asserted; enables system-level fault protection and standby mode. |
| 4 COM | Low-side return and logic ground | Common reference for VCC, IN, SD*, and LO; must be low-impedance path to minimize ground bounce. |
| 5 LO | Low-side gate drive output | Drives N-MOSFET gate referenced to COM; 600mA sink capability ensures fast turn-off. |
| 6 VS | High-side floating supply return | Reference node for high-side driver; tracks switching node voltage in bootstrap configuration. |
| 7 HO | High-side gate drive output | Drives N-MOSFET gate referenced to VS; 290mA source drives gate during bootstrap charging phase. |
| 8 VB | High-side floating supply input | Connects to bootstrap capacitor top; supplies high-side driver stage up to 600V above VS. |
Key Features
| Feature | Design Value |
|---|---|
| Floating high-side driver | Supports 600V VB–VS offset in bootstrap mode, eliminating need for isolated supplies in half-bridge topologies. |
| Integrated dead time | Hardware-generated 300–650 ns delay between HO and LO transitions prevents shoot-through without external timing components. |
| Negative transient tolerance | Outputs withstand –5V undershoot on VS and COM pins, improving reliability in high-dI/dt motor-drive PCB layouts. |
| Dual UVLO protection | Independent lockout for VCC (logic/low-side) and VB/VS (high-side) ensures safe operation during asymmetric supply faults. |
| Schmitt-triggered inputs | Hysteresis >1.7V on IN and SD* pins rejects >50ns noise spikes common in EMI-prone power systems. |

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 |
|---|---|---|---|
| IR2104PbF | Lower high-side voltage rating (600V same), but only 200mA/340mA drive; no internal dead time. | Requires external dead-time circuitry; less suitable for noise-sensitive motor drives. | Select if cost-sensitive and external timing control is acceptable. |
| UCC27201DR | Higher drive strength (4A source/4A sink), but requires external bootstrap diode and no integrated UVLO on VB. | Better for high-frequency, high-power applications (>1MHz, >5kW), but increases BOM count and layout complexity. | Select when peak gate current >600mA is required and design can accommodate external components. |
Compared with IR2104PbF and UCC27201DR, the DGD2104MS8-13 offers balanced integration-built-in dead time, dual UVLO, and 600V/290mA–600mA drive-making it optimal for industrial motor drives and mid-power SMPS where reliability and component count matter.

FAQ
What is the maximum allowable dVS/dt for the DGD2104MS8-13 high-side section?
The DGD2104MS8-13 specifies a maximum dVS/dt rating of 50 V/ns at the VS pin. This value is validated under recommended operating conditions and ensures reliable level-shifting performance during fast-switching events in high-di/dt applications like motor drives and inverters. Exceeding this rate may cause false triggering or latch-up in the high-side driver stage.
Does the DGD2104MS8-13 require an external bootstrap diode?
Yes-the DGD2104MS8-13 requires an external fast-recovery bootstrap diode (e.g., 1N4148WS or equivalent) between VB and the bootstrap capacitor's positive terminal. The IC does not integrate this diode; omission will prevent proper high-side supply charging and result in HO output failure after initial startup.
Can the DGD2104MS8-13 drive IGBTs directly without gate resistors?
No-external gate resistors are mandatory for both HO and LO outputs when driving IGBTs. The DGD2104MS8-13's 290mA/600mA drive capability is sufficient for typical IGBT gate charge, but series resistors (typically 5–22 Ω) are required to control switching speed, suppress ringing, and limit peak current during Miller plateau crossing.
Is the DGD2104MS8-13 qualified for automotive applications per AEC-Q100?
No-the DGD2104MS8-13 is not AEC-Q100 qualified. Diodes Incorporated explicitly states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; this part is rated for industrial temperature range (–40°C to +125°C) but lacks automotive qualification documentation or test reports.
