By using a single IC, a half bridge circuit can be operated in which one MOSFET is in high side configuration and another one is in the low side configuration. For driving the high side MOSFET, this IC uses a bootstrap circuit which otherwise could have to be designed externally.

Mar 19, 2012  Hi Since I have built a full bridge circuit which is exactly same to the attached diagram. 200V on the mosfet. PSU for two IR2110 driver circuit which. How to make H bridge using Mosfet driver IR2110 and H bridge for inverter. To get complete circuit diagram of H bridge comment on this post with your email address.

Before using this IC for driving the half or full bridge circuit, it is necessary to test the faultiness of the IC. A faulty IC can give unstable output and may blow up the MOSFET or other components in the circuit. In this tutorial, the method to test the IR2110 IC is discussed.

Ryuichi sakamoto albums. As in accordance to the pin configuration of IR2110, the SD (shutdown) pin is used to shutdown the IC. This pin is active high, so for enabling the IC to work, this pin is connected to the ground. The VDD is the supply voltage for driving the internal circuitry of the IC and it should be in between 3V to 20 V (with reference to Vss) as per the datasheet.

The VCC is directly connected to the drain of internal MOSFET of low side driver(as shown in internal circuit diagram of IR2110) and it can be in between 10V to 20V. For testing the IR 2110 IC, 5V is taken as VDD and 12V is taken as VCC. When the input at Lin or Hin pin is high then the IC gives High output at LO or HO pin corresponding to the input supply. When logic input at Lin and Hin are low then a low is obtained at LO and HO pin.
