| IR2110 Pin | Typical Connection | Description | | :--- | :--- | :--- | | | +5V | Logic supply input. | | HIN | Microcontroller PWM output | Signal for the high-side MOSFET. | | SD | GND | Shutdown pin; tie to ground for normal operation. | | LIN | Microcontroller PWM output | Signal for the low-side MOSFET. | | VSS | GND | Logic ground. | | VB | Positive side of Bootstrap Cap (D1 Cathode) | High-side floating supply. | | HO | Gate of High-Side MOSFET (via R1) | High-side gate drive output. | | VS | Source of High-Side MOSFET / Drain of Low-Side MOSFET | High-side floating supply return. | | VC | +12V to +20V | Low-side supply. | | LO | Gate of Low-Side MOSFET (via R2) | Low-side gate drive output. | | COM | GND | Low-side return. |
Before downloading external files from the internet—which can sometimes contain corrupted data or malware—check if your Proteus software already has it. Open and launch a new Schematic Capture project. Click on the Component Mode icon on the left toolbar.
Some third‑party models rely on .DLL files that are not compatible with Proteus 9 due to licensing changes.
Verify the folder path (using the System → Set Path menu in Proteus) and confirm that both .LIB and .IDX files are present. Restart Proteus and, if needed, run it as administrator. ir2110 library for proteus 8 link
This approach works for nearly all third‑party Proteus libraries, including IR2110 packages that come with a .LIB file.
| Pin | Name | Description | | --- | --- | --- | | 1 | VDD | Logic supply (e.g., +15 V) | | 2 | HIN | High‑side logic input (PWM) | | 3 | SD | Shutdown – usually tied to GND | | 4 | LIN | Low‑side logic input (PWM) | | 5 | VSS | Logic ground | | 6 | VB | High‑side floating supply (bootstrapped voltage) | | 7 | HO | High‑side gate output (to top MOSFET) | | 8 | VS | High‑side floating return (source of top MOSFET) | | 9 | VC | Low‑side supply – connect to VDD | | 10 | LO | Low‑side gate output (to bottom MOSFET) | | 11 | COM | Low‑side return (power ground) |
