ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1, VDCIN = VHSD = VCSSP = VCSSN = 18V, V SHDN = VVL, VCELL = GND, VBATT = VCS = 4.2V, VVADJ = VREF / 2,
VISETIN = VISETOUT = VREF, RTHM = 10k
, TA = -40°C to +85°C, unless otherwise noted.) (Note 7)
Note 1: When VISETOUT = 0, battery charger turns off.
Note 2: See Thermistor section.
Note 3: Below this threshold, charger reverts to a prequalification mode with IBATT reduced to 10% of full scale.
Note 4: Above this threshold, charger is disabled.
Note 5: 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.
