_______________________________________________________________________________________
Note 1:
When V
ISETOUT
= 0, battery charger turns off.
Note 2:
See
Thermistor
section.
Note 3:
Below this threshold, charger reverts to a prequalification mode with I
BATT
reduced to 10% of full scale.
Note 4:
Above this threshold, charger is disabled.
Note 5:
After full-charge state is complete and BATT 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.
