Note 2: Parameters are production tested at T A = +25 N C. Limits over the operating temperature range are guaranteed through
correlation using statistical quality control (SQC) methods.
Note 3: Guaranteed by design, not production tested.
Note 4: Voltage for 4.35V battery mode increases by 100mV.
Note 5: Refresh voltage for 4.15V increases by 50mV.
Note 6: JEITA decreases by 1% for 4.15V termination voltage.
Note 7: Battery overvoltage increases by 1% for 4.15V termination voltage.
* = Contact factory for alternate thresholds (6.7V, 9.7V, and 14V available).
** = Contact the factory for 3.0V.
