How to implement overcurrent protection using 'SD' pin of IR2110

[thelukuntla]

I want to implement overcurrent protection for the MOSFET inverter bridge that was driven by IR2110. How to use "SD"-pin of IR2110 for overcurrent protection.

Any application notes or suggestions are requested.

Thanks in Advance

You will need a current transducer and a comparator. To be more specific you need to provide more about the circuit and the load.

Also keep in mind that the SD input blanks both the HO and LO outputs, which may not be desirable for current limiting. Again, it depends on the specifics of the circuit and the intended goal.
