Note 1: Devices are 100% production tested at T
Note 2: V
Note 3: Guaranteed by undervoltage and overvoltage threshold testing. For charge completion, the input voltage must be greater
Note 4: This hysteresis is for all charge current except 95mA. In the case of 95mA charge current, voltage-mode to current-mode
