Ir2110 Library For Proteus 8 Upd -
The Gate Driver’s Ghost: An IR2110 Story for Proteus 8
Part 1: The Midnight Simulation
Dr. Arjun Velez stared at the blinking red line on his oscilloscope simulation. It was 2:00 AM. His high-side MOSFET in the H-bridge was supposed to be switching beautifully at 50 kHz. Instead, it was oscillating like a drunken sailor, radiating heat in the virtual world of Proteus 8.
He had the IR2110 — the legendary high-low side gate driver. But his schematic symbol was a generic, broken rectangle. He had no library for it. Without the accurate simulation model, his 500W brushless motor controller was just a fancy space heater.
“I can’t prototype a real PCB until this works in the digital twin,” he muttered, sipping cold coffee.
Proteus 8 came with many parts, but the IR2110 — with its tricky bootstrap capacitor, level shifting, and high-side floating supply — was missing. He needed to create it. Or find someone who had.
Part 2: The Forge of the Library
Arjun opened the Library Manager in Proteus 8. He decided to build the IR2110 from scratch.
First, the Schematic Symbol:
He created a new component named IR2110. Pins 1-16 appeared on his canvas: VCC, COM, HIN, LIN, SD, VB, HO, VS, LO, and the rest. He color-coded them: red for power, blue for logic inputs, green for outputs. He linked each pin to a standard SPICE model template.
Second, the PCB Footprint: He used the Package Wizard to draw a 16-pin DIP (DIL16) and a SOIC-16W for surface mount. He mapped pin 1 to the silkscreen dot, ensuring no future board house would complain.
Third, the Simulation Model (the hardest part): Proteus 8 uses SPICE and VSM (Virtual System Modelling). Arjun didn’t have the actual silicon code, so he downloaded a public .MODEL file from a university archive. He attached it to the component using the PRIMITIVE = ANALOG property.
He added a line in the model properties:
+ MODEL = IR2110.SPI
Then came the magic — he defined the Bootstrap Diode as an intrinsic property so that Proteus would simulate the high-side floating supply correctly. Without this, the HO pin would never go above VCC.
Part 3: The First Smoke Test (Digital Smoke)
With the new library saved as IR2110.LIB in the LIBRARY folder of Proteus 8, Arjun dragged his brand new component onto the schematic.
He built a test circuit:
- A 12V DC supply on VCC.
- A 15V bootstrap capacitor (10µF) between VB and VS.
- A 1N4148 diode from VCC to VB.
- Two IRF540 MOSFETs (half-bridge).
- A 100µH inductor load to ground.
- Two pulse generators: one for HIN (high input) at 50 kHz, one for LIN (low input) with 500ns dead time.
He clicked the Play button.
The simulation ran. The logic inputs toggled. LO switched the low-side MOSFET perfectly. But HO... HO stayed at 0V.
"Classic," Arjun sighed. "The bootstrap hasn't charged."
He realized his model needed the initial condition. He added a .IC V(VB)=15 in the simulation settings script. He reran. ir2110 library for proteus 8 upd
This time, the high-side gate voltage rose from 0V to 27V — 12V above the switching node. The virtual MOSFETs switched. The inductor current flowed. The simulation waveform looked beautiful.
Part 4: The Library’s Legacy
Over the next week, Arjun refined his IR2110 library for Proteus 8. He added:
- Thermal simulation (junction temperature rise)
- Under-voltage lockout (UVLO) warning — if VCC dropped below 9V, the model output an error log.
- Shutdown pin (SD) functionality — active high kills both outputs.
He shared the library on a GitHub repo and an EDA forum. Other engineers thanked him. Students used it for their final year projects: solar inverters, BLDC drivers, and even a small Tesla coil driver.
One user wrote: “Your IR2110 library saved my thesis. The real chip matched the simulation within 5%.”
Part 5: The Update (Proteus 8 UPD)
Years later, Labcenter Electronics released Proteus 8 UPD (the final service pack). They had noticed Arjun’s library’s popularity. In the new update, they officially included an optimized IR2110 VSM model — but they kept his pin mapping and footprint as the default, with a special thanks in the release notes.
Arjun smiled, watching his digital ghost now standard in thousands of simulations. The midnights of debugging had been worth it.
Epilogue: The Bootstrap Principle
Whenever a young engineer asks him, “How do I simulate a floating high-side gate driver in Proteus 8?”
Arjun replies: “Build the library yourself first. Only then will you understand the bootstrap — it’s not just a capacitor; it’s a promise of voltage above the sky.”

Title: The Bootstrap Paradox
Dr. Aris Thorne was not a patient man. He was a power electronics engineer, and in his world, traces either conducted or they didn't, MOSFETs either switched or they exploded. There was no gray area. But for the last three nights, there was only gray—a blank, gray Proteus 8 schematic screen staring back at him.
His task was brutal: design a 500W Half-Bridge converter for a brushless DC motor. The brain of this operation was the IR2110, a legendary high-voltage, high-speed MOSFET driver. It was the only chip that could handle the tricky bootstrap circuitry required to drive the high-side switch.
There was just one problem. Proteus 8 didn't have an IR2110 library.
He had tried the generic "H-Bridge Driver" from the simulation models. It failed. He tried using two discrete optocouplers and a floating supply. The simulation oscillated like a dying firefly. On the third night, at 2:00 AM, Aris slammed his coffee mug down, chipping the ceramic.
"I'll build the damned thing myself," he growled. The Gate Driver’s Ghost: An IR2110 Story for
He opened the Proteus 8 Device Update Package (DUP) tool—a clunky interface that allowed custom component creation. He named the new part: IR2110_CUSTOM.
First, the Graphical Symbol. He drew the sixteen pins: Vcc on pin 1, COM on pin 2, LO on pin 7, VS on pin 6, HO on pin 7... wait. He squinted at the datasheet. He had swapped pins 5 and 7. He sighed, deleted it, and drew it again. Perfect.
Second, the PCB Footprint. He assigned it a standard DIP-16. Easy.
Third, the Spice Model. This was the soul of the machine. He didn't have a raw transistor-level model. He only had the behavioral description from the manufacturer: "A high-voltage, high-speed power MOSFET driver with dependent current sources and a bootstrap diode."
Aris was a purist. He opened the subcircuit file and began typing:
.SUBCKT IR2110 VCC HIN LIN SD COM VSS VS HO LO
He coded the undervoltage lockout (UVLO) as a voltage-controlled switch. He coded the propagation delay as a 50ns transmission line. He coded the infamous bootstrap action—the heart of the chip—as a charge pump that only activated when VS dipped below VCC.
He hit "Save" and ran the DUP Compiler.
Error: Node count mismatch.
He had forgotten the "VB" pin (Bootstrap Supply). At 3:30 AM, he added it. He re-compiled.
Success. Model compiled.
He dragged his new IR2110_CUSTOM onto the schematic. He added a 12V logic supply, two IRF540 MOSFETs, a 100uF bootstrap capacitor, a 1N4148 diode, and a 12V resistive load. He connected the high-side gate to HO, the low-side gate to LO, and the switch-node to VS.
He held his breath. He clicked the Play button.
The simulation ran. For 10 milliseconds, nothing happened. Then, the high-side gate voltage plotted on the oscilloscope. It was... flat. Zero volts.
"Worthless," he whispered.
But then he saw it. The bootstrap capacitor was at 0V. It never charged. He forgot to add the diode between VCC and VB inside the model definition. He had modeled the driver as perfect, but real life required the diode.
At 4:45 AM, he edited the subcircuit again:
D_BOOT VB VCC DIODE_1N4148
He recompiled. He re-ran.
The simulation started. For the first 20 cycles, the high-side output was weak—only 8 volts. Aris zoomed in. The bootstrap cap was sipping charge every time the low-side MOSFET turned on, pulling the VS pin to ground. Then, on the 21st cycle, the high-side gate voltage jumped.
11.8V.
The MOSFET switched hard. The load current waveform turned into a perfect, crisp square wave. 500 watts of simulated power pulsed through the virtual wires.
Aris leaned back. The chipped coffee mug was empty. His eyes burned. But on the screen, his custom IR2110 library for Proteus 8 was singing.
He saved the library file as IR2110_UPDATED_FINAL_REAL.LIB and closed the laptop.
Outside, the sun was rising over the city. The half-bridge converter was working. The MOSFETs were switching. And Dr. Aris Thorne had finally won.
The lesson, as he would write in his engineering blog the next day: "If Proteus doesn't have the part, don't wait for an update. Build the paradox yourself. Just don't forget the bootstrap diode."
Option 2: Create a Simulation Equivalent (Recommended)

2. GitHub Repositories
Repositories like Proteus-Libraries or Power-Electronics-Simulation often contain IR2110 parts. Look for files named IR2110.IDX and IR2110.LIB.
Future of IR2110 Modeling in Proteus
With the rise of Proteus 8 UPD’s VSM Studio and co-simulation with SPICE3F5, some users have successfully imported the official Infineon IR2110 SPICE subcircuit. This requires editing the .CIR file into a .MLN format using the VSM SDK – a process beyond basic users but worth exploring for research.
Infineon (which acquired International Rectifier) now provides free SPICE models. A community effort to convert these into a unified Proteus library would be invaluable.
Common Errors and Troubleshooting (IR2110 Library for Proteus 8 UPD)
Even with a good library, you may face errors:
| Error | Probable Cause | Solution |
|-------|---------------|----------|
| "Unknown part IR2110" | Library not indexed | Restart Proteus; re-add library path |
| "Model not found" | Missing .MODEL statement | Add MODEL=IR2110 in component properties |
| Simulation fails at bootstrap | No initial low-side pulse | Add a startup circuit or initial condition for bootstrap cap |
| Floating node error | VS node not referenced | Connect VS to load midpoint, not floating |
| "Time step too small" | High dV/dt causing convergence issue | Reduce simulation speed; add snubbers or increase deadtime |
If none of the above works, consider using an alternative approach: model the IR2110 behavior using a combination of:
- Voltage-controlled switches
- Logic gates (AND, NOT)
- Pulse transformers
But this defeats the purpose of a dedicated library.
