Electrical Characteristics
APM8601 is tested at VDC = VUSB = 5V, VBAT = 4V, V EN = 0V, RSETI = 2kΩ, CCT = 68nF, at an ambient temperature of +25°C
unless otherwise noted.
Note:
5. Guaranteed by testing of undervoltage- and overvoltage-threshold. To completely charge a battery cell, the input voltage must be greater than 4.32V.
