6V(Typical).

Trickle Charge Mode

At the beginning of a charge cycle, if the battery voltage is below 5.6%V, the charger goes into trickle

charge mode with the charge current reduced to 15% of the full-scale current.

Charge Current Setting

The full-scale charge current, namely the charge current in constant current mode, is decided by the

following formula:

Where:

End-of-Over Charge Current Setting

End-of-over charge current can be set by connecting a resistor from EOC pin to GND, and is decided by

the following equation:
