Ir2110 Library For Proteus 8 Online

The Ultimate Guide to the IR2110 Library for Proteus 8: Download, Installation, and Simulation

Components Required (besides IR2110):

Two N-channel MOSFETs (e.g., IRF840 or IRFZ44N from Proteus library)
Bootstrap diode (1N4148 or UF4007)
Bootstrap capacitor (10µF to 47µF, 25V)
Two gate resistors (10Ω to 22Ω)
12V DC for VCC (low-side supply)
100V DC for bus voltage (use 100V source)
Two 10k pull-down resistors on inputs
Pulse sources for HIN and LIN (from Generator Mode)

Introduction

The IR2110 is a high-voltage, high-speed half-bridge gate driver commonly used to drive N-channel MOSFETs and IGBTs in motor drives, power converters, and inverter circuits. For Proteus 8 users, a reliable IR2110 library component (with correct symbol, footprint, and functional model) streamlines simulation of gate-drive timing, bootstrap operation, and switching behavior. This post explains key requirements, how to obtain or create a quality IR2110 library for Proteus 8, validation tips, common pitfalls, and an example testbench.

Part 2: Does Proteus 8 Come with an IR2110 Model by Default?

No. The default Proteus 8 library (version 8.0 to 8.9) includes generic MOSFET drivers like the TC4420 or IR2101, but the IR2110 is notably absent. Even in the "Active" or "Simulation" library categories, you will not find a fully functional simulation model for the IR2110.

Some older versions have a symbolic footprint but no SPICE model attached. If you try to simulate a circuit using the existing "IR2110" symbol in some third-party libraries, you may receive errors like:

"Model not found"
"No simulation model specified"
"Pin count mismatch"

Thus, you must manually add the IR2110 library. ir2110 library for proteus 8

Alternatives to the IR2110 Library in Proteus 8

If you cannot get the library to work, or you prefer built-in parts, consider these options:

IR2101/IR2102/IR2104 – These are present in some Proteus 8 versions (check under “IR” manufacturer). They are similar to IR2110 but lower voltage (200V vs 500V).
Build a macro model – Using the Proteus Spice primitive switches and controlled sources. Advanced, but possible. The Ultimate Guide to the IR2110 Library for
Use LTSpice or Tina – Then import netlist to Proteus. Not ideal.
Use TLP250 (opto-isolated driver) – Found in Proteus libraries. But lacks high-side floating channel.

The dedicated IR2110 library remains the best choice. Two N-channel MOSFETs (e

Part 7: Alternatives if IR2110 Library Still Fails

If you cannot get the IR2110 library to work in Proteus 8, consider these alternatives:

Use IR2101 / IR2104 – Both are available in newer Proteus libraries and have similar functionality (though lower voltage rating).
Use a generic gate driver with behavioral model – Build your own using AND gates, buffers, and voltage-controlled switches.
Switch to LTspice or SIMetrix – These tools have official IR2110 models from Infineon. Simulate there and then use Proteus only for microcontroller logic.
Proteus VSM for Power Electronics – Upgrade to a Proteus version that includes the Power Electronics add-on, which may contain the IR2110.

1. The Level Shifter

The IR2110 can drive a gate referenced up to 500V above ground. This library respects the VS (Floating Offset) pin. If you forget to connect the bootstrap ground reference, the simulation correctly fails. If you wire it correctly, the high-side output fires beautifully.

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 |
