Lithium-Ion Battery Charge Control IC



This IC is linear charge control IC for 1–cell Li–ion and Li-polymer battery.
This IC does not require externally provided sensing resistor
or reverse-current protection diode, enabling reductions in the
component count and the amount of generated heat.

Function to charge control (OFF) at high/low battery temperature ensures safety of battery.
