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.

This IC is battery temperature profile compliant, Function to limit charging current and voltage in low and high battery temperature ensures safety of battery.

Built-in 2ch charge status flag can be confirmed status in detail.
