1
Undervoltage lockout generated normally from ISO_Sx or ISO_Bx; in certain transition cases, it can be generated from VINx.
2
These values are programmable via I
2
C. Values are given with default register values.
3
The output current during charging may be limited by the input current limit or by the isothermal charging mode.
4
During weak charging mode, the charger provides at least 20 mA of charging current via the trickle charge branch to the battery unless trickle charging is disabled.
Any residual current, which is not required by the system, is also used to charge the battery.

Either JEITA1 (default) or JEITA2 can be selected in I

C, or both JEITA functions can enabled or disabled in I
