I use the formula that IOUT_CAL_GAIN(trimmed) = IOUT_CAL_GAIN(untrimed) x [ (Iout2 - Iout1) / (Read_Iout2 - Read_Iout1) and IOUT_CAL_OFFSET = Iout3 - Read_Iout3.
After calibra, our modules will report OCP fault when the load is 12A. And the OCP fault is 15.5A. The calibration error is 3.5A. And the iout is brcame badly. I want to know that how can i use IOUT_CAL_GAIN and IOUT_CAL_OFFSET for calculate the iout. It can help me that whether the calbration data is wrong.
Another question is which is the target value. Iout or Read_Iout?
Thank you very mcuh!
