The AT1461 series Lithium-Ion (Li-Ion) and Lithium-Polymer (Li-Pol) linear charge ICs are designed for compact portable electronics. It provides accurate constant-current/constant voltage charging. The constant charge current is programmable with an external signal resistor. The constant voltage is 4.2V and that accuracy of the voltage regulation is better than ±1% over the operating-temperature and supply-voltage ranges.
