Note 2: Limits are 100% production tested at T
Note 3: The USB/DC current limit does not include the VL output current. See the VL Linear Regulator section for more information.
Note 4: Quiescent current excludes the energy needed for the REG1–REG5 external resistor-dividers. All typical operating charac-

Note 6: The charger transitions from fast-charge to top-off mode at this top-off threshold (Figure 7).
Note 7: The maximum output current is guaranteed by correlation to the p-channel current-limit threshold, p-channel on-resistance,
Note 8: The step-down output voltages are 1% high with no load due to the load-line architecture. When calculating the external
