4.20V / 4.35V / 4.40V correspondence One Cell Li-battery Linear Charger IC with Battery Temperature Detection

The XC6808 is a Constant-Voltage and Constant-Current linear charger for single-cell Li-ion and Li-polymer batteries.

When the input supply is removed, XC6808 automatically enters a low battery sink state, reduce the battery sink current to 0.1uA (typ.). This IC supports temperature control based on JEITA, it possible to safely charge batteries by controlling the charge voltage(CV) and charge current(CC) according to the temperature. The basic charging cycle consists of trickle charge mode followed by main charge mode. By connecting a resistor to the charge status output pin, it is possible to check the charge condition via the charge status output (CSO) pin voltage. The IC is housed in the small and low profile USP-6B07 package, and a charge circuit can be configured using a minimum of external components.
