Note 5:
When V ISETOUT = 0, battery charger turns off.
See Thermistor section.
Below this threshold, charger reverts to a prequalification mode with I BATT reduced to 10% of full scale.
Above this threshold, charger is disabled.
After full-charge state is complete and peak inductor current falls below this threshold, FULLCHG output switches high.
Battery charging continues until top-off timeout occurs. See Table 1.
Note 6: After charging is complete, when BATT voltage falls below this threshold, a new charging cycle is initiated.
Note 7: Specifications to -40°C are guaranteed by design, not production tested.
