STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics
Characteristics noted under conditions V IN = 5.0 V, -40°C ≤ T A ≤ 85°C, C IN = C OUT = 1.0 μ F (see Figure 1 ), unless otherwise
noted. Typical values noted reflect the approximate parameter means at V IN = 5.0 V and T A = 25°C under nominal conditions,
unless otherwise noted.

Supply current does not include the current delivered to the battery through the BAT pin.
In the test mode, the charger still operates in CV mode after EOC.
