Ir2110 Library For Proteus 8 »
To use the IR2110 MOSFET/IGBT Driver in Proteus 8, you typically need to add an external library if it isn't included in your standard installation. This driver is essential for simulations involving high-side and low-side switching in H-bridges, motor controllers, and inverters. Installation Guide

- The high-side output floats indefinitely.
- The bootstrap capacitor never charges.
- Students assume their PCB design is faulty when, in reality, the simulation was lying to them.
The Power Stage:
Example circuit snippet:
Want a quick test? Connect VDD = 15V, HIN = 5V PWM (1-10kHz), LIN = complementary PWM, bootstrap cap = 22µF, load between VS and ground. Watch HO swing above VDD! To use the IR2110 MOSFET/IGBT Driver in Proteus
Common Pitfalls and How to Avoid Them
- Missing bootstrap model: Without a bootstrap diode+cap the high-side driver won’t work correctly.
- Incorrect pin orientation: Leads to wiring mistakes and simulation failures—match datasheet.
- Overly ideal outputs: Zero output impedance causes unrealistic instantaneous switching; add series resistance.
- Numerical instability: Very fast edges or zero series resistance can cause SPICE convergence problems—use small R and C damping as needed.
- Neglecting UVLO and dead-time: Real drivers include these protections—omitting them can produce unrealistic cross-conduction results.
