is a high-speed, high-voltage power MOSFET and IGBT driver with independent high and low side referenced output channels. It is widely used in power electronics for applications such as bridge circuits, motor controllers, and DC-DC converters. In simulation environments like
Proteus SPICE sometimes struggles with floating nodes. For the high-side driver to work in simulation, ensure your half-bridge midpoint (VS pin) is connected to the node between the two MOSFETs, and that node has a to ground (e.g., 10kΩ) to define a DC path.
Many Proteus users have discovered that the IR2110 is missing from their library, but the is present. Because the two devices share a very similar architecture, the IR2112 can often be used as a substitute in simulation, provided you keep the following differences in mind:
The IR2110 does have built-in dead-time. In simulation, you must generate HIN and LIN with overlapping protection. Use a D-type flip-flop and RC delay, or simply offset the pulse generators manually. ir2110 proteus library
pin, which allows for cycle-by-cycle edge-triggered shutdown logic for circuit protection. Using the IR2110 Library in Proteus
If you only get a .lib file, it may still work; but for accurate simulation, the .mod SPICE model is critical.
A very common puzzle: the low‑side output (LO) works correctly, but the high‑side output (HO) remains low. The solution almost always lies in the bootstrap circuit. is a high-speed, high-voltage power MOSFET and IGBT
Components available natively in Proteus (or easily found):
: Uses a bootstrap circuit to generate the floating high-side gate voltage required to turn on upper N-channel MOSFETs. Why You Need an External Proteus Library
Driving DC motors using the IR2110's high and low side outputs to control direction and speed via PWM. For the high-side driver to work in simulation,
Connect HO to the gate of the high-side MOSFET through a 10-ohm resistor.
Simulating power circuits in Proteus is a standard practice for engineers. While Proteus includes many basic components, users often search for or create specific IR2110 library files to ensure the simulation accounts for actual hardware behaviors. Simulation Fidelity
For highly simplified testing, an IR2110 can be approximated using:
When using an IR2110 library in Proteus, the simulation must accurately reflect three core features:
