BQ297xy Overcurrent protection
From the datasheet:  


  The discharge overcurrent detection voltage (VOCD) is measured between
  V–and VSS pins and triggered when the V2 voltage is increased above
  VOCD threshold with respect to VSS. This delta voltage once satisfied
  will trigger an internal timer tOCDD before the DOUT output drive
  transitions from high to low.  


There is no user setting where he/she can individually change the settings. The thresholds can be either set at the factory or use parts with pre fixed factory thresholds.
