Product details
Overview
DGD2388MS20-13 from Diodes Incorporated is a three-phase half-bridge gate driver IC for N-channel MOSFETs and IGBTs in motor inverter applications, featuring 600V high-side bootstrap operation, 420mA source / 750mA sink output current, 315ns internal deadtime, and -40°C to +125°C operating range.
For engineers reviewing the DGD2388MS20-13 datasheet, DGD2388MS20-13 pinout, DGD2388MS20-13 application, or DGD2388MS20-13 equivalent, key selection criteria include high-voltage floating channel timing matching (≤50ns), Schmitt-triggered 3.3V-compatible logic inputs, and independent UVLO per high-side supply (VB/VS).
Technical Context
The DGD2388MS20-13 integrates six independent gate drive channels-three high-side (HO1–HO3) referenced to floating VS1–VS3 supplies and three low-side (LO1–LO3) referenced to COM-with matched propagation delay (≤50ns) and integrated shoot-through prevention logic that forces both outputs low when HINx and LINx are simultaneously high.
It employs bootstrap high-side biasing with dedicated VBx/VSx terminals per phase, supports dVS/dt up to 50 V/ns, and implements dual undervoltage lockout: VCCUV (7.1–9.9V threshold) for logic/low-side supply and VBSUV (same threshold range) per high-side channel, ensuring safe turn-off during supply sag.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 600V max VS-to-VB offset; enables use with 400V DC bus inverters without external level-shifting. |
| Output Drive Strength | 420mA source / 750mA sink; sufficient to rapidly charge/discharge 1000pF gate capacitance in <75ns rise/fall. |
| Internal Deadtime | 315ns typical; prevents cross-conduction in half-bridge legs without external timing circuitry. |
| Logic Input Compatibility | 3.3V–5V TTL/CMOS; allows direct interface with microcontrollers and FPGA I/O without level translation. |
| Propagation Delay Matching | ≤50ns max mismatch across all six channels; ensures synchronized switching across three phases. |
| Operating Temperature | -40°C to +125°C ambient; qualified for industrial motor drives and white goods under thermal stress. |
| UVLO Thresholds | VCCUV+/VBSUV+ = 7.1–9.9V; hysteresis of ~0.4V prevents oscillation near trip point during supply transients. |
Pinout & Package
Package: SO-20 (Type TH), surface-mount, lead-free, RoHS-compliant molded plastic with matte tin-plated leads and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5 (HIN1–HIN3) | High-side logic input | In-phase control signal for HO1–HO3; Schmitt-triggered, 3.3V-compatible, enable-low default. |
| 2, 4, 6 (LIN1–LIN3) | Low-side logic input | In-phase control signal for LO1–LO3; identical electrical specs to HIN pins; shoot-through logic active. |
| 7, 13, 17 (LO3–LO1) | Low-side gate output | Driving N-MOSFET/IGBT gates referenced to COM; 750mA sink capability minimizes turn-off delay. |
| 8, 14, 19 (VS3–VS1) | High-side floating return | Source node reference for each high-side driver; must be connected to respective phase leg source terminal. |
| 9, 15, 19 (HO3–HO1) | High-side gate output | Drives high-side device gates; referenced to VSx; 420mA source current supports fast turn-on. |
| 10, 16, 20 (VB3–VB1) | High-side bootstrap supply | Provides floating bias for HOx drivers; requires external bootstrap capacitor per phase (e.g., 0.1µF ceramic). |
| 11 (COM) | Low-side & logic ground | Common return for LOx outputs, VCC, and all logic inputs; must be low-inductance connection to PCB ground plane. |
| 12 (VCC) | Fixed low-side supply | 10–20V input powering logic core and LOx drivers; includes UVLO with 8.5V nominal trip point. |
Key Features
| Feature | Design Value |
|---|---|
| Three floating high-side drivers | Each supports 600V VS-to-VB differential; eliminates need for isolated supplies or level-shifters in 3-phase inverters. |
| Matched propagation delay | ≤50ns max skew across all six outputs; maintains phase alignment critical for vector-controlled motor drives. |
| Integrated shoot-through protection | Hardware logic forces HOx/LOx low when HINx and LINx both high; prevents destructive shoot-through without software intervention. |
| Schmitt-triggered inputs | Hysteresis >1.6V on 0.8V/2.4V thresholds; rejects noise in high-dV/dt motor drive environments. |
| Dual independent UVLO | VCCUV and per-channel VBSUV with separate thresholds and hysteresis; ensures safe shutdown even if only one supply fails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2136JTRPBF | Higher 600V high-side rating but no integrated shoot-through logic; requires external logic or MCU coordination. | Lacks hardware-level fault prevention; suitable where system-level control already manages cross-conduction. | Select when existing firmware handles deadtime and shoot-through detection, and higher VBS transient immunity is needed. |
| UCC27211D | Single-channel dual-output (high/low) with 4A peak drive; requires three units for 3-phase vs. single DGD2388MS20-13. | Higher drive strength but larger board area and BOM count; no integrated multi-phase timing coordination. | Select when extreme gate current (>1A) is required per leg and layout flexibility outweighs integration benefits. |
Compared with IR2136JTRPBF and UCC27211D, the DGD2388MS20-13 delivers full 3-phase integration with hardware shoot-through protection and matched timing in one SO-20 package-reducing component count, PCB area, and firmware complexity for industrial and appliance motor drives.

FAQ
What is the maximum recommended dVS/dt for DGD2388MS20-13?
The datasheet specifies a maximum dVS/dt rating of 50 V/ns. Exceeding this value risks false triggering of high-side drivers due to capacitive coupling through the internal level-shifting circuitry. Layout best practices-including short, low-inductance VS traces and local decoupling-must be followed to maintain robustness at high switching speeds.
Can DGD2388MS20-13 drive IGBTs directly?
Yes-the DGD2388MS20-13 is explicitly rated for IGBT driving, with 420mA source and 750mA sink output current sufficient for typical 15–50A IGBTs used in motor inverters. Its 600V high-side rating and integrated UVLO make it suitable for IGBT-based 400V DC bus applications without external protection circuitry.
Is there a minimum pulse width requirement for HIN/LIN inputs?
Yes-the datasheet recommends a minimum input pulse width of 600ns for reliable logic recognition, especially at 3.3V levels. Shorter pulses may not register due to internal filtering and Schmitt trigger hysteresis; this constraint applies to all six input channels (HIN1–3, LIN1–3).
How does the shoot-through protection logic behave during fault conditions?
When both HINx and LINx are high simultaneously, the internal logic forces the corresponding HOx and LOx outputs low-regardless of input state-until at least one input returns low. This hardware-level action occurs within nanoseconds and is independent of VCC or VB supply status, providing fail-safe protection against destructive shoot-through.
