Ir2110 Library For Proteus 8 May 2026
The IR2110 is a high-speed, high-voltage MOSFET and IGBT driver used extensively in power electronics for bridge circuits. Because it is not always available in the default installation of Proteus 8, users often need to manually add an external library to simulate power converter designs. 1. Why Use the IR2110 in Proteus?
High-Side and Low-Side Driving: It can drive MOSFETs at voltages up to 600V, making it essential for H-bridge and half-bridge simulations.
Logic Compatibility: Its input logic is compatible with standard CMOS or LSTTL outputs down to 3.3V, allowing it to interface directly with microcontrollers like Arduino.
Bootstrap Integration: It handles the high-side floating supply through a bootstrap circuit, which can be accurately modeled in Proteus to test capacitor and diode performance. 2. How to Add the IR2110 Library to Proteus 8
Adding the library generally involves two main methods depending on the file format you have downloaded: ir2110 library for proteus 8
Manual File Placement (.LIB and .IDX files)If you downloaded a custom library folder (common on hobbyist forums):
Locate the Library Folder: Right-click your Proteus 8 icon and select Open File Location. Navigate up one level to find the folder named LIBRARY.
Copy Files: Move the downloaded .LIB and .IDX files (usually named IR2110.LIB or similar) into this directory.
Restart Proteus: The software must be closed and reopened to recognize the new library components. The IR2110 is a high-speed, high-voltage MOSFET and
Importing via SnapMagic (.pdif files)If you downloaded the part from professional repositories like SnapMagic: Open Schematic Capture. Go to Library > Import Parts.
Select the .pdif file and follow the prompts to add the part to your local database. 3. Simulation Checklist
To ensure the IR2110 works correctly in your Proteus schematic: Power Supplies: Ensure VCCcap V sub cap C cap C end-sub (Low-side supply) and VDDcap V sub cap D cap D end-sub (Logic supply) are correctly connected. VSScap V sub cap S cap S end-sub must be connected to the digital ground.
Bootstrap Circuit: Place a bootstrap capacitor (typically 0.1µF to 1µF) between the VB and VS pins and a fast recovery diode between VCCcap V sub cap C cap C end-sub and VB. and Simulate MOSFET Drivers
Output Pins: Connect HO (High-side Output) and LO (Low-side Output) to the gates of your respective MOSFETs.

Common Errors and Troubleshooting
Even after installation, users often encounter issues. Below is a troubleshooting table.
| Error Message / Symptom | Likely Cause | Solution | |------------------------|--------------|----------| | “Unknown part IR2110” | Library not indexed | Reinstall using Method 1 or check spelling | | “Model not found” | Missing .LIB file or broken model definition | Download from a different source | | Simulation runs but HO stays low | VS pin not connected to MOSFET source | Connect VS directly to high-side source | | Floating node error | VSS not grounded | Tie VSS and COM together to ground | | High-side output never charges | No bootstrap action – missing diode/cap | Add bootstrap diode from VCC to VB and cap from VB to VS | | IR2110 pins not visible in schematic | .IDX file missing or corrupt | Re-extract archive or use another IR2110 library |
1. Component Overview
- Library Name:
IR2110.PDSLIB - Model Type: Mixed-mode (SPICE + digital logic)
- Purpose: High-voltage, high-speed gate driver for N-channel MOSFETs/IGBTs in half-bridge and low-side configurations.
Q4: Why does my simulation run extremely slowly?
Complex SPICE models can slow down Proteus. Try increasing the TMAXSTEP or use a simpler primitive model for the IR2110.
