Outline
This IC is linear charge control IC for 1–cell Li–ion and Li-polymer battery.
This IC can control accurate charge current (3 to 500mA),so it is suitable small and low current consumption IC for mobile devices used low-capacitance battery.
This IC have multiple rank matched charge voltage for each battery (4.1V to 4.45V) and can be individually set Full-charge current,so various charging systems can be constructed.
Low BAT leak current contributes to extending the usage time of mobile devices.
