ELECTRICAL CHARACTERISTICS (continued)
(V
are at T
Note 1: Limits are 100% production tested at T
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
Note 4: Guaranteed by the current-limit test.
