Hello great bot lords :-) I was wondering - do you know of a current sense IC that can detect currents 30 A; or can only those "hall effect" current sensors get there? I would perfer to find an IC because the hall effect sensors have that big copper core in the middile - this means more $$.
Any ideas?

Digikey only has them going up to 7A . . .
You can always run a few in parallel, and in post processing multiply the output by the number you have in parallel.

Ok, that would work.... but it end up costing more $$ in the end. Looks like i'm going with the hall effect. Thank you!
Btw, I love your site - thank you for this wonderful resource.

Hi there is an NT-XX series of current sensors. They are available in 5,15,25, and 50 amp IC's.

sdk32285, their cheapest one is $25, almost 3x the hall effect option . . . ;D

Heres an even cheaper option.

request a sample. :o

Any idea what the max current that can handle? I can't seem to find that data, andn wouldn't want to burn it out.

+/- 5 - 30A
