VDDIN: The status indicator (Read Only) of supply voltage V
set high when V
VDDIN is set inactive low.
: ADDRESS 0AH
ENCCref: Enable constant current regulation reference current.
ENCC: Enables the constant current regulation for constant current charge with desired current
amount selected.
unimplemented
The 3-bits select CURSEL[3:0] selects constant current regulation reference current. The
regulation current accuracy is 10% (unless otherwise noted).
: ADDRESS 0BH
ENCVref: Enable constant voltage regulation reference current.
ENCV: Enables the constant voltage regulation for constant voltage charge with desired voltage
amount selected.
unimplemented
The 3-bits VOLSEL[3:0] selects constant voltage regulation reference voltage. The regulation
voltage accuracy is ±1%.
