IR2110

The IR2110/IR2113 are high voltage, high speed power MOSFET and IGBT drivers with independent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with

standard CMOS or LSTTL output, down to 3.3V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use in high frequency applications. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high side configuration which operates up to 500 or 600 volts.

What is IR2110

IR2110 is a MOSFET gate driver IC that can used to drive high and low side configurations. Usually to drive two MOSFETs in half bridge or high and low side configuration we will need complicated driver circuit with complementary transistors dual voltage supplies and lots of other complementary devices such as resistors, capacitors and diodes. However, we can achieve the same function using  IR2110 MOSFET driver IC only using few other complementary components. You can see the physical appearance of the IR2110 MOSFET driver IC in below image.
