The function of PIN CSP and 5mR resistor is to do Over Current Proection(OCP). If you do not use this pin then CCG3PA will lose OCP feature.
In addition, the PPS function will also be lost.
But I think 2W Power consumption for 5mR shunt resistor is too big because even if current goes up to 5A Power on 5mR is only 125mW. a 0805 package resistor is enough. How do you think of it?
Thanks and Best regards
Yes, I think it's applicable.
