By following these steps, you can now simulate high-side gate drive circuits with bootstrap operation entirely within Proteus 8. This will save you time, reduce prototyping errors, and deepen your understanding of gate drive dynamics.
The IR2110 is exceptionally efficient for driving a single low-side MOSFET in a buck converter. By utilizing the LIN input, you can boost a 5V microcontroller PWM signal to a 12V-15V gate drive, maximizing the efficiency of the power MOSFET.
: Its input logic is compatible with standard CMOS or LSTTL outputs down to 3.3V, allowing it to interface directly with microcontrollers like Arduino. ir2110 library for proteus 8
Ensure you are pulsing the Low-Side MOSFET ( LIN ) first . The bootstrap capacitor only charges when the low-side MOSFET is turned on, pulling the VS pin to ground. If you apply a continuous high signal to HIN without cycling LIN , the bootstrap capacitor will discharge and the high-side gate drive will fail. 3. Invalid/No Simulator Model
While you can easily find a visual schematic symbol for the IR2110 in some extended component lists, it usually lacks the underlying SPICE simulation model. If you try to run a simulation with it, Proteus will throw a "No simulator model found" error. By following these steps, you can now simulate
C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY
Driven by a bootstrap circuit, allowing it to operate up to +500V. Low-Side Channel: Referenced to the power ground. By utilizing the LIN input, you can boost
When you run the simulation in Proteus 8:
Place a 10kΩ resistor between VS and GND. This gives a discharge path for the bootstrap capacitor during initial power-up, allowing simulation to converge.
Proteus 8 comes with extensive libraries under the Analog ICs and Mixed Mode categories. However, for reasons related to licensing, model complexity, or manufacturer-specific IP, many power driver ICs like the IR2110 are absent.
Before jumping into the simulation, it is essential to understand why the IR2110 requires careful setup in Proteus.
