Product details
Overview
DGD0636MS28-13 from Diodes Incorporated is a three-phase half-bridge gate driver IC for N-channel MOSFETs and IGBTs, featuring 100V high-side bootstrap operation, 200mA source / 350mA sink output current, 290ns internal deadtime, -40°C to +125°C operating range, and SO-28 (Type TH) package-used in BLDC motor inverters for power tools and robotics.
For engineers reviewing the DGD0636MS28-13 datasheet, DGD0636MS28-13 pinout, DGD0636MS28-13 application, or DGD0636MS28-13 equivalent, key selection criteria include bootstrap voltage tolerance, shoot-through protection logic, fault-clear timing adjustability via RCIN, and TTL/CMOS-compatible 3.3V logic inputs in high-noise industrial environments.
Technical Context
The DGD0636MS28-13 integrates six independent gate drivers-three high-side (HO1–HO3) with floating VS/VB supplies and three low-side (LO1–LO3) referenced to COM-with matched propagation delays (≤50ns) and built-in cross-conduction prevention. Its logic inputs are Schmitt-triggered and inverted relative to outputs.
Protection architecture includes dual UVLO (VCC and VB), overcurrent detection via ITRIP analog input (420–600mV threshold), open-drain FAULT output (FO*), and RCIN-adjustable auto-fault-clear timing (1.6ms typical with 1nF). All channels shut down simultaneously during fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 100V bootstrap operation enables use with 600V-class IGBTs/MOSFETs in 3-phase inverter legs |
| Output Drive Strength | 200mA source / 350mA sink ensures fast turn-on/turn-off of gate capacitances up to ~4.7nF at 15V |
| Internal Deadtime | 290ns fixed deadtime prevents shoot-through during high-frequency PWM switching (e.g., >20kHz) |
| Logic Compatibility | 3.3V-tolerant TTL/CMOS inputs simplify interface with microcontrollers and FPGAs without level-shifting |
| Thermal Range | -40°C to +125°C junction temperature supports operation in enclosed industrial enclosures and motor housings |
| Fault Response Time | ITRIP-to-output shutdown delay ≤820ns ensures rapid gate disable during overcurrent events |
| Propagation Matching | ≤50ns delay mismatch across all six channels maintains phase alignment in multi-leg motor control |
Pinout & Package
Package: SO-28 (Type TH), surface-mount, lead-free, RoHS-compliant molded plastic with matte tin-plated leads and 0.250g mass. Moisture sensitivity level 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Fixed low-side and logic supply input (10–20V); powers internal logic and LO drivers |
| 2–4 | HIN1*, HIN2*, HIN3* | Inverted logic inputs for HO1–HO3; active-low, Schmitt-triggered, 3.3V compatible |
| 5–7 | LIN1*, LIN2*, LIN3* | Inverted logic inputs for LO1–LO3; same electrical specs as HIN pins |
| 8 | FO* | Open-drain fault output asserted low on VCC UVLO or overcurrent; requires external pull-up |

| 17, 21, 25 | NC | No internal connection; must be left unconnected or grounded per layout guidelines |
| 18, 22, 26 | VS3, VS2, VS1 | Floating high-side return nodes; each tied to respective leg's source terminal |
| 19, 23, 27 | HO3, HO2, HO1 | High-side gate drive outputs; referenced to corresponding VS pin, bootstrap-biased |
| 20, 24, 28 | VB3, VB2, VB1 | Bootstrap supply inputs; each charges external capacitor to bias HO outputs above VS |
Key Features
| Feature | Design Value |
|---|---|
| Three floating high-side drivers | Enables independent bootstrap biasing for each phase leg up to 100V offset, supporting 3-phase inverter topologies without isolated supplies |
| Matched propagation delay | ≤50ns channel-to-channel skew ensures synchronized switching across all six outputs, critical for torque ripple reduction in BLDC control |
| Outputs out of phase with inputs | Inverted logic interface eliminates need for external inverters, reducing BOM count and PCB area in compact motor drives |
| dV/dt immune high-side inputs | Withstands 50V/ns transients on VS pins, preventing false triggering during fast-switching transitions in high-power inverters |
| Adjustable fault-clear timing | RCIN pin allows system designers to tune recovery delay post-fault (e.g., 100µs to 10ms), avoiding nuisance tripping during transient overload |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2330MTRPBF | Higher 600V high-side rating but no integrated ITRIP input; uses external comparator for overcurrent | Requires additional components for current fault detection; better suited for high-voltage (>400V) industrial drives | Select if system operates >200V bus and needs higher voltage margin; avoid if space-constrained or shunt-based sensing preferred |
| UCC27211D | Single-channel dual-output (high/low) with 4A peak drive; no integrated deadtime or fault logic | Needs external deadtime generation and fault management circuitry; used in custom multi-phase designs | Select for ultra-high-speed switching (>100kHz) where discrete timing control is required; not drop-in for DGD0636M's integrated protection |
Compared with IRS2330MTRPBF and UCC27211D, the DGD0636MS28-13 delivers integrated overcurrent sensing, programmable fault recovery, and matched timing in a single SO-28 package-reducing design complexity and PCB footprint for mid-voltage (≤100V bootstrap) BLDC inverters.

FAQ
What is the maximum bootstrap voltage supported by the DGD0636MS28-13?
The DGD0636MS28-13 supports a high-side floating supply (VB) up to +124V absolute maximum, with recommended operating range of VS +10V to VS +20V and a functional offset limit of VS ≤ +100V. This enables reliable 100V bootstrap operation for driving 600V-class power devices in 3-phase configurations.
How does the ITRIP pin function in overcurrent protection?
The ITRIP pin accepts an analog voltage from a current-sense resistor or amplifier. When voltage exceeds 420–600mV (typical 500mV), the device asserts FO* low and shuts down all six outputs within ≤820ns. Leading-edge blanking (200–400ns) prevents false triggering during switching transients.
Can the DGD0636MS28-13 drive both MOSFETs and IGBTs?
Yes-the DGD0636MS28-13 is explicitly designed to drive both N-channel MOSFETs and IGBTs in half-bridge configurations. Its 200mA source / 350mA sink capability, 100V bootstrap rating, and negative transient tolerance make it suitable for IGBT gate charge requirements and MOSFET Miller plateau crossing.
Is the SO-28 (Type TH) package thermally enhanced?
The SO-28 (Type TH) package has a thermal resistance of RθJA = 60°C/W on a standard 2-layer JEDEC FR-4 board. While not a thermally flagged package like exposed-pad variants, its 2.3W power dissipation rating and 45°C/W RθJC support continuous operation at full drive strength up to +125°C ambient when properly laid out with adequate copper pour.
