selected.
Select CURSEL[3:0] set constant current regulation reference current.
The regulation current accuracy is ±10% (unless otherwise noted).
If Enables ENCC, ENCV must be Disables.
Current sensing using an external sensing resistor RSNS=0.22ohm.
Through selecting V
Enable ENCVref can be constant voltage regulation reference current.
ENCV=1 enables the constant voltage regulation for constant voltage charge with desired voltage amount
select VOLSEL[3:0] set constant voltage regulation reference voltage.
The regulation voltage accuracy is ±1%.
If enables ENCV, ENCC must be Disables.
