AC current sensing

Hi team,

Could you recommend current sensing IC for output below?

This is AC output, so isolated device should be needed.

Total is 10ch. It doesn't have to be 10ch at once, but multi-channel the better.

++ It is for automotive application, so Q1 would be neccessary.

More regarding questions...

1) Is TMCS1101A1B-Q1 able to detect AC 48V 0.05A?

2) For voltage sensing iso amp, what would be the best fit in 12V, simply used for battery monitoring? I was thinking of AMC1x11-Q1.

3) Do we have iso CAN SIC?

Hi Zena,

For AMC, AMC1200-Q1 or AMC1300B-Q1 could be considered.

As this is only a 48V application, INA devices with a high common-mode voltage may be considered as well.

The other devices are owned by other product lines, you may want to move the post or post again to their forums.

Could you recommend other AMC devices for voltage sensing also? I've noticed that AMC1200 and 1300 is for current sensing.

Thanks.

Sure, AMC3330 or AMC1350 have bipolar input ranges, ideal for AC voltage sensing.
