ELECTRICAL CHARACTERISTICS (continued)

PV13 = PV2 = SYS, T
Note 3: Limits are 100% production tested at T
Note 4: The charger transitions from done to fast-charge mode at this BAT recharge threshold.
Note 5: The charger transitions from fast-charge to top-off mode at this top-off threshold (Figure 2).
Note 6: The maximum output current is guaranteed by correlation to the p-channel current-limit threshold, p-channel on-resistance,
Note 7: The step-down output voltages are 1% high with no load due to the load-line architecture.
Note 8: The skip-mode current threshold is the transition point between fixed-frequency PWM operation and skip-mode operation.
Note 9: Line regulation for the step-down converters is measured as ∆V
Note 10: REG2 is disabled by connecting PV2 to ground, decreasing the quiescent current.

n-channel on-resistance, oscillator frequency, input voltage range, and output voltage range. The parameter is stated for
a 4.7µH inductor with 0.13Ω series resistance. See the Step-Down Converter Maximum Output Current section for more
information.
The specification is given in terms of output load current for inductor values shown in the typical application circuit (Figure 1).
