Part Number: CSD95480RWJ

customer want to check if CSD95480 can meet +/- 4% current sense accuracy at below condition range?

: Vin=7V to 13.2V range, Vo=0.6V~3.3v range，Vdrvi=5V, Tj=25C~125C ,25A<Iout<45A

if CSD95480 can't meet +/- 4% current sense accuracy,

is there any other device can meet this requirement and it is p2p with CSD95480 ?

thanks.

Hi Max,

The CSD95480 can deliver current sense accuracy of ~4.25% at 25A and 105C. By 30A the accuracy will be under 4% and continue getting better at higher currents. The accuracy will get slightly worse as the temperature increases and better as the temperature decreases towards room temperature. The current sense is not very sensitive to changes in VIN and VOUT. This is currently the most accurate current sensing power stage we offer, but check back as we plan to release products with even better current sense accuracy later this year!

Regards,
Evan
