Hello,
I wish to do load short circuit protection with a differential opamp (please see link)

Do you think this will work?.....it just has to catch the flyaway short circuit current and stop it reasonably quickly.......if short circuit happens, then there will be periodic high current pulses from the battery , but this is better than high current all the time........the FET keeps getting switched back on to allow resumption of operation when the short is removed
Battery current when load is short circuit....

LTC1841 opamp DATASHEET

The differential opamp doesnt have to be particularly accurate......but it does have to work....will common mode effects stop it from working suitably in this application?
