Diodes Incorporated DGD2136S28-13

Overview

DGD2136S28-13 from Diodes Incorporated is a three-phase half-bridge gate driver IC designed to control N-channel MOSFETs and IGBTs in motor inverter stages. It features 600V high-side bootstrap operation, 200mA source / 350mA sink output current, 290ns internal deadtime, matched propagation delay (<50ns), and operates from -40°C to +125°C in SO-28 package - deployed in air conditioner compressor inverters.

For engineers reviewing the DGD2136S28-13 datasheet, DGD2136S28-13 pinout, DGD2136S28-13 application, or DGD2136S28-13 equivalent, key selection criteria include high-voltage floating supply tolerance (VS up to 600V), shoot-through prevention logic, adjustable fault-clear timing via RCIN, and TTL/CMOS-compatible 3.3V logic inputs with Schmitt triggering for noise immunity.

Technical Context

The DGD2136 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 cross-conduction prevention logic that forces both outputs low when HIN* and LIN* are simultaneously high. Its bootstrap architecture enables high-side switching up to 600V with dV/dt immunity of 50 V/ns.

Protection functions include VCC and VB undervoltage lockout (UVLO thresholds at 7.1–9.9V), overcurrent shutdown triggered by ITRIP (420–600mV threshold), and open-drain fault output (FO*) with automatic recovery timed by external RC on RCIN. All channels share matched AC timing: tON/tOFF = 200–460ns, tDT = 200–420ns, tDM < 50ns.

FAQ

Is DGD2136S28-13 still in active production?

No - Diodes Incorporated has officially discontinued the DGD2136S28-13 and marked it as obsolete. However, Aetrix Electronics maintains legacy inventory with full traceability and offers technical support for existing designs. Replacement guidance toward functionally aligned alternatives like IRS2330MTRPBF is available upon request.

What is the correct layout practice for VSS and COM pins?

Per Diodes' Design Notes (DS38611 Rev. 7–4, pp. 11–12), VSS and COM must be shorted together directly at the SO-28 package body - not at the controller MCU or distant ground plane. This local tie minimizes ground loop inductance and prevents false fault triggering during high-di/dt startup events in compressor applications.

How does the ITRIP pin interface with a current-sense amplifier?

The ITRIP pin accepts a single-ended analog voltage (400–600mV threshold) from a current-sense amplifier's output. It features 340–500mV hysteresis and 200–400ns blanking time to ignore switching noise. No external filtering is needed - the internal comparator directly triggers FO* and shuts down all six outputs within 420–820ns of overcurrent detection.

Can DGD2136S28-13 drive SiC MOSFETs?

No - the DGD2136S28-13 is characterized and specified only for silicon MOSFETs and IGBTs. Its 350mA sink current, 150ns rise time, and 600V VB rating do not meet the gate drive requirements of typical SiC devices, which demand faster edge rates, higher peak current, and tighter timing control. Use dedicated SiC gate drivers such as UCC21530 or ISOS6610 for such applications.
