When using the IR2110 in Proteus, ensures your input signal logic ( VDDcap V cap D cap D ) matches the controller ( ) and your gate drive power ( VCCcap V cap C cap C ) is sufficient (usually ir2110 proteus library
Proteus is a popular simulation software used for designing and testing electronic circuits. It offers a wide range of features and tools for simulating and analyzing electronic circuits, including: I can provide a step-by-step guide to wiring
| 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. | | | "Unknown subcircuit called for IR2110" |
The IR2110 uses a bootstrap capacitor to generate a voltage higher than the supply rail for the high-side gate driver. Without simulation, debugging floating gate drive circuits often leads to blown MOSFETs or mysterious oscillations. Proteus allows you to see what happens inside the bootstrap circuit before soldering a single component.
Device overview
High-side MOSFETs require a gate voltage higher than the supply voltage to turn on. Proteus models the IR2110’s bootstrap circuit, which uses an external capacitor and diode to "lift" the gate voltage. Logic Compatibility: It typically accepts 3.3V or 5V logic inputs at the
