Ir2110 Library For Proteus 8 [repack]

Proteus offers real-time animation. A working library allows you to see the voltage swings on the gate of the MOSFETs, making it easier to troubleshoot why a motor might not be spinning or why a converter isn't switching. Integration Challenges

Also copy any model file like IR2110.MOD or .HEX into the MODELS folder:

Search for "IR2110 library for Proteus" on forums like ⁠The Engineering Projects or GitHub.

The simulation will fail if there is no load or low-side connection pulling the VS pin down to ground initially. Ensure a half-bridge configuration is properly wired to charge the bootstrap capacitor when the low-side switch activates.

| Pin | Name | Description | |------|-------|-----------------| | 1 | LO | Low-side gate drive output | | 2 | COM | Low-side return | | 3 | VCC | Low-side supply (10–20V) | | 4 | N/C | Not connected | | 5 | VS | High-side floating offset | | 6 | VB | High-side floating supply | | 7 | HO | High-side gate drive output | | 8 | N/C | Not connected | | 9 | VDD | Logic supply (3.3–20V) | | 10 | HIN | High-side input | | 11 | SD | Shutdown (active high) | | 12 | LIN | Low-side input | | 13 | VSS | Logic ground | | 14 | N/C | Not connected |

| Error Message | Likely Cause | Solution | |---------------|---------------|----------| | "Unknown part IR2110" | Library not loaded | Restart Proteus; check LIBRARY folder | | "Model not found" | .MDF file missing | Copy IR2110.MDF to MODELS folder | | "SPICE model error" | Incompatible syntax | Use .MODEL directive or recompile | | "No DC path to ground" | Bootstrap cap not charging | Add a weak resistor (100k) from VS to GND | | "HO always low" | VB voltage too low | Ensure bootstrap cap > 1µF and diode is fast |

If building a model seems intimidating and you need a quick simulation, there's a widely known and effective workaround: use the .

Driven by a bootstrap circuit, allowing it to operate up to +500V. Low-Side Channel: Referenced to the power ground.

High-side floating supply voltage (connected to the bootstrap capacitor). HO (Pin 7): High-side gate drive output. The simulation will fail if there is no
