Note 1: Limits are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design
and characterization.
Note 2: Input refers to either DC or USB.
Note 3: Guaranteed by undervoltage- and overvoltage-threshold testing. For complete charging, the input voltage must be greater
than 4.32V.
