The most common application of the IR2110 is creating a half-bridge driver to control two MOSFETs. Essential Components: IR2110 MOSFETs: IRF540 or IRF840 Diode: 1N4007 or fast-recovery diode (for bootstrapping) Capacitor: (Bootstrap Capacitor) Sources: Pulse Voltage Generator (for HIN/LIN), DC supply, High Voltage supply ( Key Connections to Remember: Low-Side Setup: Connect VCCcap V sub cap C cap C end-sub COMcap C cap O cap M VSScap V sub cap S cap S end-sub to Ground. Bootstrap Diode: Connect the cathode of the 1N4007 to VBcap V sub cap B (Pin 12) and the anode to VCCcap V sub cap C cap C end-sub Bootstrap Capacitor: Connect between VBcap V sub cap B (Pin 12) and VScap V sub cap S High-Side Output: Connect VScap V sub cap S
The IR2110 features delay matching of 10ns, making it highly efficient for high-frequency switching applications. Its floating channel can operate up to 500V (or 600V for IR2113), making it suitable for a wide range of power conversion tasks. ir2110 proteus library
If you download a custom .LIB and .IDX file for the IR2110, follow these steps: : Unzip the downloaded files. Copy : Locate the IR2110.LIB and IR2110.IDX files. The most common application of the IR2110 is
Ensure your low-side MOSFET is turning on periodically. The bootstrap capacitor only charges when the low-side switch pulls the VS pin down to COM/GND . If you run a 100% duty cycle on the high side, the floating supply will drain, and the high-side output will turn off. 5.

The IR2112 is extremely similar to the IR2110, with the key difference being its logic supply voltage ( VDD ). It is designed to operate with a 5V logic supply, making it directly compatible with 5V microcontrollers without level shifting. Many Proteus users have confirmed that the IR2112 model is included in the default library and works properly for simulation, even when the IR2110 model is missing or buggy. In most simulation contexts, the IR2112 can serve as a drop-in functional replacement.
Ideal for motor control, switched-mode power supplies (SMPS), and inverters.
