Note 1:

×
V
VADJ
).
Note 2:
This transconductance is for one cell. Divide by number of cells to determine actual transconductance.
Note 3:
See
Thermistor
section.
Note 4:
Below this threshold, the charger reverts to prequalification mode and I
CHG
is reduced to about 5% of full scale.
Note 5:
Above this threshold, the charger returns to reset.
Note 6:
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.
Note 7:
After charging is complete, when BATT voltage falls below this threshold, a new charging cycle is initiated.
Note 8:
In shutdown, charging ceases and battery drain current drops to 5μA (max), but internal IC bias current remains on.
Note 9:
Specifications to -40°C are guaranteed by design and not production tested.
