Ir2110 Proteus Library May 2026
The IR2110 is one of the most popular high-voltage, high-speed MOSFET and IGBT drivers used by electronics engineers and hobbyists. When designing power electronics like motor drivers, inverters, and SMPS, simulating your circuit in Proteus before hardware fabrication is a crucial step to save time and prevent component damage.
- Use a compiler (like MikroC Pro for PIC or SDCC) to compile the logic above into a
.hexor.cofffile. - Alternatively, you can download an existing IR2110.dll or IR2110.mdl file created by the Proteus community (commonly found on engineering forums like "Proteus 8 Professional > MODELS").
2. Bootstrap Capacitor Calculation
In simulation, use: [ C_boot > \frac2 \times Q_g\Delta V_boot ] For IRFZ44N (Qg ~ 60nC), 47µF is safe. In Proteus, too small a capacitor will cause high-side voltage to droop. ir2110 proteus library
| Error Message | Cause | Solution |
|---------------|-------|----------|
| "Component not found" | Library files not in correct folder | Verify path; try putting .lib in both LIBRARY and USERLIB folders. |
| "Unknown subcircuit called for IR2110" | Missing SPICE model | Copy the .mod file into MODELS folder and edit the component’s “Model File” property. |
| "Pin ‘VB’ not found" | Wrong library version (only 14-pin vs 16-pin) | IR2110 is 16-pin. Delete the old component and re-add from correct library. |
| "Simulation fails with ‘time step too small’" | Circuit deadlock or missing bootstrap cap | Add a bootstrap capacitor (10µF to 100µF) and a fast recovery diode. Reduce simulation max time step to 1ns. |
| "High side gate output always low" | Bootstrapping not working in simulation | In Proteus, you may need to add initial conditions: use IC=0 for the bootstrap cap node or enable startup option in Transient Analysis. | The IR2110 is one of the most popular
Example Simulation
Bootstrap Capacitor: Essential for the high-side driver to function; usually a small capacitor (e.g., 1uF) connected between the VBcap V sub cap B VScap V sub cap S Use a compiler (like MikroC Pro for PIC
