Note 1: BYP internally connects to the active power input (DCLV or USB). DCLV takes priority if both inputs are powered.
Note 2: These limits guarantee +5 ° C accuracy with 5% accuracy of thermistor beta (3450 nominal) with 2 ° C of hysteresis.
Note 3: The CHG output does not go high unless charge current is below the indicated threshold (as set by DCI) and the charger is in
voltage-mode operation. In 100mA USB mode, CHG goes high when the charger transitions from current to voltage mode.
Note 4: Specifications to -40 ° C are guaranteed by design, not production tested.
