20 / 91 page  ACT2861QI Rev 2.0, 27-Apr-2018 Innovative PowerTM www.active-semi.com ActiveSwitcherTM is a trademark of Active-Semi Copyright © 2018 Active-Semi, Inc. 20 Figure 3: Operating Modes State Machine voltage is above the VBATSHORT voltage when enter- ing this state, the charger still charges at the ISHRT cur- rent for 16ms before moving to the Precondition state. During this state, the Low Battery Safety Timer is run- ning to detect fault conditions or bad battery. See the Charge Safety Timers section for further details. The Low Battery Safety Timer is a cumulative timer for the SCOND, and PCOND states and is fixed at 2 hours. A Safety Timer timeout or Battery OV during this state causes the charger to move to the Fault State, which disables charging. An input voltage OV or UV condition also moves the state machine into the Fault state. Fi- nally, a fault on the VREG LDO, which is not masked with the DIS_CHG_VREG_FLT register also moves the state machine into the Fault state. During this state, the VIN voltage and VIN Current reg- ulation loops are active to ensure the input supply power ratings are not exceeded. Additionally, the thermal reg- ulation loop is active to keep the ACT2861 junction tem- perature at or below the desired maximum junction tem- perature. See the appropriate sections for more details. During this state the nCHG pin is pulled low to indicate charging is in progress. Battery Short Condition Temp Suspend (SCSUS- PEND) This state prevents charging when the battery tempera- ture measured by the TH pin exceeds the JEITA or Bat- tery Temp registers settings for Hot or Cold. All switch- ing stops and charging is suspended. The state ma- chine only enters SCSUSPEND from the SCOND state. The charger transitions back to the SCOND state and |
