Hi. Infineon
In my application; use 3172P to design in type-C adapter. now, the QC2.0 and QC3.0 OCP test data as below,230V AC input ,the QC2.0 and QC3.0 12V2.5A and 20V 1.5A OCP test result is 3.44A and 2.32A. I try to modify the battery.charging.h QC_AMP_20V(300 -->210 and 110) and QC_AMP_12V(300-->110 and 90) , but the test ressult without any change. would you like to let me know where to change to let the OCP meet customer requirement. and add schematic in here.
thanks

Just post a resolution -
CCG_MAX_PDP_VALUE and LEGACY_MAX_CABLE_RATING should not be set to 0. Instead, the Macros should be set just like below -
#define CCG_MAX_PDP_VALUE 255u
#define LEGACY_MAX_CABLE_RATING 400u
#define CCG_POWER_PRECISION_MULT 100000u
Inside the API qc_set_cf_limit()the OCP threshold would be set. In addition, the OCP limit can also be set manually.

Hi Flance,
Just let me know if you have enabled the QC OCP (macro in config.h: QC_CF_EN) in your firmware?
Thanks,
Fred
