MM3835W
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 1000mA),so it is suitable for
mobile devices used low-capacitance battery.
This IC have multiple rank matched charge voltage for each battery (4.20V, 4.35V, 4.1V).
Charging voltage and current can be controlled safely according to the battery temperature based on JEITA guideline.
