To interface the NE555P Timer (IC1) with the IR2110 High/Low Side MOSFET Driver (U1), you can create a simple circuit to generate a PWM (Pulse Width Modulated) signal from the 555 Timer and feed this to the gate driver.
Here's how you might go about making those connections:
  1. Connect VCC (Pin 8) and GND (Pin 1) of IC1 to your power source. Make sure the source is suitable for the input voltage range of the NE555P.
  2. Connect DIS (Pin 7) to VCC (Pin 8) with a pull-up resistor, let's assume a value of ${R1=4.7k\Omega}$.
  3. From the THR (Pin 6) to VCC (Pin 8), connect a capacitor ${C1=10nF}$.
  4. Connect TR (Pin 2) to THR (Pin 6)
  5. Connect CV (Pin 5) to GND (Pin 1) using a decoupling capacitor, let's assume a value of ${C2=1nF}$.
  6. Connect R (Pin 4) to VCC (Pin 8).
That sets up your 555 timer as an oscillator that emits a PWM signal on its output Q (Pin 3). The frequency and duty cycle of the PWM signal depends on the values of ${R1}$ and ${C1}$.
Now, let's connect it to the gate driver (U1):
  1. Connect Q (Pin 3) of IC1 to LIN (Pin 14) of U1. This will provide a PWM input to the low side inverter input.
  2. Connect the COM (Pin 2), VSS (Pin 15), and VS (Pin 6) of U1 to the ground of your power source.
  3. Connect VCC (Pin 3) and VDD (Pin 11) of U1 to your power source. Make sure it is in the suitable range for the IR2110.
  4. For testing purposes, you may initially leave HIN (Pin 12) of U1 disconnected, or you can connect it to ground via a resistor, e.g., ${10k\Omega}$.
  5. SD (Pin 13) can also be left unconnected or connected to VDD.
(Note, however, that in more complex cases you might want to use a microcontroller to feed the LIN and HIN inputs to provide separate control over the high side and the low side, and you will usually need to connect VB (Pin 7) and HO (Pin 8) in order to drive a MOSFET or IGBT, but these steps aren't necessary for a basic interface test.)
Feel free to tweak and adjust these assumptions as per your actual requirements, this setup is a good starting point and doesn't cover every consideration.
