ELECTRICAL CHARACTERISTICS (continued)
(VUSB = VDC = VDCLV = VEN = VUSEL = 5V, VBATT = 4.2V, VTHRM = VREF / 2, Circuit of Figure 2, TA = -40°C to +85°C, unless otherwise
noted. Typical values are at TA = +25°C.) (Note 4)

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.
