Diodes Incorporated DGD2136MS28-13

Overview

DGD2136MS28-13 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, 200mA source / 350mA sink output drive, 290ns internal deadtime, -40°C to +125°C operating range, and SO-28 package.

For engineers reviewing the DGD2136MS28-13 datasheet, DGD2136MS28-13 pinout, DGD2136MS28-13 application, or DGD2136MS28-13 equivalent, key selection criteria include high-voltage floating supply tolerance (624V abs max), dV/dt immunity, shoot-through prevention logic, adjustable fault-clear timing via RCIN, and TTL/CMOS-compatible 3.3V logic inputs.

Technical Context

The DGD2136MS28-13 integrates six independent gate drivers-three high-side (HO1–HO3) referenced to floating VSx supplies and three low-side (LO1–LO3) referenced to COM-with matched propagation delays (≤50ns mismatch) and out-of-phase input-output logic. Its bootstrap architecture supports up to 600V high-side offset with dV/dt immunity of 50V/ns.

Protection is implemented via dual UVLO (VCC and VB), overcurrent detection at ITRIP (400–600mV threshold), and automatic fault clear timed by external RC on RCIN. Fault output FO* is open-drain and asserts on either UVLO or overcurrent events.

FAQ

What is the maximum allowable dV/dt at the VS pins?

The DGD2136MS28-13 is rated for 50 V/ns dV/dt at the VS pins, enabling robust operation in high-speed switching applications with fast-rising bus voltages. This specification is verified per datasheet Absolute Maximum Ratings and ensures reliable high-side floating operation without false triggering or latch-up under typical inverter edge rates.

How does the shoot-through protection logic function?

The shoot-through protection logic monitors all HIN* and LIN* inputs simultaneously and forces both corresponding HOx and LOx outputs low if both inputs are asserted high. This hardware-level blocking occurs independently of propagation delay and prevents destructive cross-conduction, even during logic glitches or controller faults.

Can the DGD2136MS28-13 drive IGBTs directly without external gate resistors?

While the DGD2136MS28-13 provides 200mA source and 350mA sink current, external gate resistors are still required to control switching speed, suppress ringing, and limit peak current into IGBT gate capacitance. The datasheet recommends resistor values based on target rise/fall times and EMI constraints - typically 5–22Ω for 1200V IGBTs in motor drives.

What is the purpose of the RCIN pin and how is it configured?

The RCIN pin accepts an external RC network to set the fault-clear timeout after overcurrent or UVLO events. With a 1nF capacitor and 2MΩ resistor, the typical clear time is 1.6ms. This allows temporary overload conditions (e.g., motor startup surge) to self-recover without system reset, while maintaining safety-critical shutdown for sustained faults.
