Dear All
V have got a controller which generates overcurrent alarm
We need to know which IC monitors current in the loop and generates overcurrent alarm
This PCB has got following ICs viz SN75173N, 75172N, 75C188,9829,75C189A,TDKT ZJYS4
Will it be possible to tell which of the above ICs is to monitor current and generate error in case of overcurrent as v need to locate that IC and replace because physical conditions r ok and no error comes after replacing PCB with new one that means overcurrent detector is only faulty
Regards,
