Hi, Lisa
Our product is 1C1A application and C port OCP trigger point is 3.6A .
if enabling QC_CF_EN and A port entering QC2 mode , and A port voltage change from 5V to 9V or 12V, then C port OCP trigger point become 3A, why?
if disabling QC_CF_EN and A port entering QC2 mode , and A port voltage change from 5V to 9V or 12V, then C port OCP trigger point still is 3.6A
