    Once the handover battery voltage threshold is reached to enter direct charging; the main charger is disabled and the DA9318 is enabled with a target battery charge current of 5.5 A. Upon assertion of the E_VBAT_WARN event, the TA current is reduced allowing for a smaller charge current;...
  • Page 34 When the charge current reaches a handover charge current threshold (arbitrarily set to 0.9 A) the DA9318 is switched off and the main charger is enabled and finishes off the charge cycle. The main charger continues its fast charge and voltage regulation phase until the termination current is reach where the main charger will get disabled.
