Note 1: Limits are 100% production tested at TA = +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.
