LP4030H Standalone 1-4 Cell 3A Battery Charger
■The LP4030H family is highly integrated switching charger for 1-4 cells of Li-Ion and Li-Polymer batteries.
■The devices support 4.5V to 20V operation input voltage and charge current is up to 3A. The BAT pin withstands a voltage up to 28V, which is designed for protecting the devices from an over-shoot voltage in battery application systems.
■The devices provide various safety features for battery charging, including battery under/over temperature protection, device junction over temperature and cycle-by-cycle inductor current limit protection. The input voltage regulation loop reduces charge current when the input source capacity is not enough to provide the programmed charge current. The STAT output indicates the charging status.
■The LP4030H family is available in a DFN-10(3x3mm) package.
