G'day All,

I've bee searching for an isolated DC current sensor, I came across this one shown in the attached picture. It's very nice looking, however I'm looking for the manufactures PN of the actual IC component. I purchased the little circuit in the attached but when it arrived the main part had it's identification numbers scratched off! An email to the seller also didn't amount to anything. Anyone have any ideas?

Are you sure this is for 100A, dont look like. This circuit use hall sensor, you can search hall sensors.
 

Brilliant stuff YAS_HASHI! that's would have to be the one I reckon! nice little device according the data sheet. And yep... according to the datasheet it is 100A dual direction sensing device. ACS756SCA-100B-PFF-T.
 

That is a pretty neat device, thanks for posting about it. It's nice to see companies trying to miniaturize high power hall effect sensors; this is a potential replacement for much bulkier sensors like those made from LEM, if you can tolerate the relatively inaccurate output.
