For more detail I recommend you to go through datasheet of IR2210 and one tip for those readers who are from Pakistan, Don’t purchase IR2110 from Pakistan.I have successfully designed H bridge after making many changes in H bridge with 33uf/50v bootstrap capacitor value. you should use bootstrap capacitor value 22uf-40uf. It plays a very important rule in H bridge of pure sine wave inverter. The bootstrap capacitor used between VB and VS to fully operate high side MOSFET.VB pin 6 is used as a high side floating supply of floating circuit to provide floating voltage to high side MOSFET.In return, your circuit will stop working. For example in over voltage or over current protection circuit, if any of these values become greater than specified values, you can give a 5-volt signal to shutdown IR2210 driver to stop driving MOSFETS. you can use it for the protection circuit. But input signal logic level should also be between 4-5 volt. It may be from a microcontroller or any other device. LIN pin 12 is an input signal for low side Mosfet driver output.But input signal logic level should be between 4-5 volt.
HIN pin 10 is an input signal for high side MOSFET driver output.But if you used voltage less than 4 volts it may not give you the required result. When hen input to low side at pin 12 Lin is low, LO output will be equal to the value of VSS and it means zero. Because when an input to the low side at pin 12 Lin is high, LO output will be equal to the value of Vcc voltage at pin 3 with respect to Vss and COM pin. It is at the same potential as ground VSS pin 13. pin2 is a return path for the low side.Pin 1 is the output of low side MOSFET drive.
To know about totem pole output and its used a Mosfet driver go through the following article: Because it has low input impedance and high drive current. But almost all MOSFET drivers used totem pole output. There are many types of MOSFET drivers available in the market. MOSFET drivers are used to avoiding these issues. This problem is known as the miller effect. High voltage on the drain of MOSFET cause problem by interaction with gate-drain capacitance. One can do it very easily but there is one issue. Why we need a MOSFET driver? Because MOSFETs are voltage control devices and used to drive MOSFET the gate capacitance should be charged to operating voltage which is usually between 9-10 volt. How to use a MOSFET driver? MOSFET driver circuits are used to drive MOSFETS in a high side or low side. It can drive both low side and high side switches in half-bridge and low bridge circuits. IR2110 is a high voltage MOSFET driver IC.
