Ir2110 Library For Proteus 8 Upd 'link' -

Story: IR2110 Library Update for Proteus 8

Raj scrolled through the forum, eyes scanning threads from hobbyists and students frustrated by a missing IR2110 driver in Proteus 8. He’d fought the same battle: trying to simulate a half-bridge MOSFET driver, only to find Proteus’ component library lacked a ready-made, well-behaved IR2110 model. The result was patched-together circuits, unreliable logic-level behavior, and simulation runs that ended with unexplained floating nodes.

He decided to fix it.

Step 1 — Understanding. Raj pulled the IR2110 datasheet and read it cover to cover. He noted the bootstrap diode timing, the high-side floating supply (HB), the logic thresholds for HIN/LIN, undervoltage lockout behavior, and the MOSFET gate-source current dynamics during switching. He sketched how Proteus’ SPICE primitive components would need to interact: a level-shifted high-side driver, a bootstrap circuit, UVLO comparators, and proper gate output stage impedance.

Step 2 — Building the symbol. Using Proteus’ library editor, Raj drew a clear, compact symbol: VCC, COM, VB, VS, HIN, LIN, HO, LO, and SD. He added visible pins for bootstrapping (BOOT diode and cap placement in the reference schematic) and labeled pins to match typical PCB footprints so others could drop the symbol into designs without confusion.

Step 3 —The behavioral model. Proteus lacked an official IR2110 SPICE model, so Raj built a behavioral macro: comparators for UVLO, controlled sources to emulate the high-side floating reference, timed switches for the bootstrap recharge window, and the gate drivers’ output stage with realistic Rg and saturation characteristics. He tuned the LO and HO output drive strengths and dead-time behavior to match datasheet rise/fall times across typical gate capacitances.

Step 4 —Validation. Raj created a testbench in Proteus: a half-bridge with two MOSFETs, a bootstrap cap and diode, logic pulses to HIN/LIN, and a resistive load. He ran edge-case tests: continuous high-side duty cycles long enough to reveal bootstrap recharge limits, rapid switching patterns, and undervoltage scenarios. He compared simulated HO/LO voltages and VB-VS waveforms to datasheet waveforms and corrected timing mismatches and output slew rates.

Step 5 —Documentation and sharing. He packaged the library with a short example schematic, a recommended bootstrap capacitor value table, notes on required MOSFET gate resistances for stable results, and an explanation of the UVLO thresholds used in the model. Raj posted the package to the community forum with a changelog titled “IR2110 Library for Proteus 8 — Updated behavioral model, accurate bootstrap/UVLO, v1.0” and a brief usage guide.

The response was immediate. Students who had been unable to simulate a functioning bootstrapped high-side driver posted screenshots of clean HO/VS waveforms. A power-electronics professor thanked him for saving lab hours. A hobbyist adapted the model to test synchronous buck prototypes. Someone suggested improvements — adding temperature-dependent behavior — and Raj planned a follow-up release.

Weeks later, a community-maintained repository listed Raj’s IR2110 library among the top contributions for Proteus 8. He felt satisfied not because of recognition, but because circuits now behaved in simulation the way they did on his bench: predictable, reproducible, and ready for the next iteration.

Option 3: Use Proteus 8.9 or Newer

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. Story: IR2110 Library Update for Proteus 8 Raj

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.

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. Proteus 8

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."

Testing the IR2110 Library with a Half-Bridge Circuit

After successful installation, test the library using a basic half-bridge:
