Hi Team,
I got an inquiry from one of my customers on what would be the best current sense solution for their application below:
I need some assistance in determining the error of my current sense circuit (resistor + amplifier + ADC). My requirement is +/-2000ppm/degC (Stability at 25degC) and 100ppm/degC for the entire operating temperature for 250A of current. The 250A will be provided by multiple PSUs and each PSU has its own amplifier and sensing to regulate the current. The BW for the CSA >360kHz.
I wish to determine which Current Sense IC will fit this requirement, the sensing will be low side so the Vcm would have to start from 0 or a little negative.
Do let me know if there are any other requirements that you may need to find the best part to propose :)
Thanks!
Best Regards,
Alfred
