TMCS1100: TMCS1100 insulation

Part Number: TMCS1100

Hello! Willing to use "TMCS1100" in a three phase 380Vac Motor circuit, as current sensor: I'm not quite sure if +-600V insulation of the device is enough.

TI says: ".......Inherent galvanic insulation provides a 600-V lifetime working voltage and 3-kVRMS basic isolation between the current path and circuitry"

But I'd like to get some opinion.

 

Thanks for any reply

    Hello Luigi,

    Thanks for considering to use Texas Instruments.  If you look at section 7.6 of the datasheet, you will find a table devoted to insulation specifications.  Here you can see the conditions which correspond to those voltage values that I presume you saw in the cover page description.  The 600V corresponds to more of a DC condition whereas 3000 corresponds to a transient condition.  What kind of transient voltages do you expect to see with your motor circuit?
