Hello all,
I'm using the CIPOS to drive an AC motor and my target is to reach 10 Arms phase motor current.
I set the shunt resistors are 0.03 Ohm.
after few seconds the temperature of the shunt is 150 °C because the power on each resistor is 3 W.
Please could you indicate a typical value of shunt resistor for reaching 10 Arms current on the load?
Thanks

Hi AndreaC,
please have a look at the application note: AN2016-12 from the CIPOS IGCM20F20FA webpage, under application notes.
There you get an idea on how to calculate the shunt resistor and what our application engineer used for the reference design.
For the shunt, we generally recommend high power SMD components to be used in order to reduce the stray inductance. This are available from different manufacturers of passive components.
