5.5End-of-charge current setting resistors R10 and R11

The end-of-charge (EOC) current for both the AC charger and the USB charger can be set by the resistors R10 and R11.

On the evaluation board, two resistors with one pin header jumper are used for the user to conveniently configure different EOC current values. Table 3 shows the EOC current with the different settings of pin header J12.
