: Obtain the library files (usually a ZIP folder) from reputable sites like The Engineering Projects or GitHub .
C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY ProgramData is often hidden). Paste Files : Copy the downloaded files and paste them into this folder. Restart Proteus : Close and reopen the software to refresh the database. The Engineering Projects 3. Import via Proteus Web Search
Adding a verified third-party .IDX and .LIB file pair solves this issue. It populates both the visual schematic symbol and the underlying behavioral model. Step-by-Step Guide to Installing the IR2110 Library
Paste them directly into the folder located in Step 2.
). To fix this, open > Set Simulation Options in Proteus and change the solver settings to Relaxed or increase the ABSTOL and VNTOL tolerances. ir2110 library for proteus 8
Click on the button (the "P" icon on the left toolbar). In the Keywords search box, type IR2110 .
Obtaining a library for a workhorse component like the IR2110 has become much simpler in recent Proteus versions. The key takeaway is:
I can provide a step-by-step wiring guide or calculation for your bootstrap components. Share public link
Proteus 8 uses a different folder structure than older versions (like Proteus 7). Follow these exact steps to ensure the software recognizes the new component. Step 1: Locate the Proteus 8 Library Directory : Obtain the library files (usually a ZIP
– These are present in some Proteus 8 versions (check under “IR” manufacturer). They are similar to IR2110 but lower voltage (200V vs 500V).
| IR2110 Pin | Connection | |------------|-------------| | VDD (Pin 9) | +5V (logic supply) | | VCC (Pin 1) | +12V to +15V (gate drive supply) | | COM (Pin 2) | Ground | | HIN (Pin 10) | High-side PWM input | | LIN (Pin 12) | Low-side PWM input | | SD (Pin 11) | Ground (shutdown disabled) | | VB (Pin 8) | Bootstrap cap positive (to 12V via diode) | | HO (Pin 7) | Gate of high-side MOSFET | | VS (Pin 6) | Source of high-side MOSFET & Bootstrap cap negative | | LO (Pin 5) | Gate of low-side MOSFET | | VSS (Pin 4) | Ground |
To achieve a successful interactive simulation, wire the IR2110 pins according to standard application rules:
Solution: Ensure you downloaded a "Simulation Model Library" rather than a simple CAD design symbol library. Look for a corresponding .MDF or .SPICE file package. Cause: Files were pasted into the wrong folder. Restart Proteus : Close and reopen the software
Integrating the IR2110 driver library into Proteus 8 bridges the gap between digital control logic and high-power circuit simulation. By following this guide, you can confidently analyze switching waveforms, prevent shoot-through conditions, and optimize bootstrap networks entirely inside a safe virtual environment before manufacturing your physical PCB.
: Move the .LIB and .IDX files into the Proteus LIBRARY folder.
: Fully compatible with CMOS and LSTTL logic levels down to 3.3V, though VDD is often set to a default of 5V in Proteus for standard operation. Protection Mechanisms
