Results forLP4030

The LP40300 is a standalone 1-cell swilching baltery charger providing up to 3.5A charge current lo the battery from 4.1v lo 6.2V input voltage. The charge current is programmable by a resistor connected from ISET to GND and the charge voltage is programmable by a resislor connected from VSET to GND. The charge can be enabled and disabled from ISET pin. The LP40300 operates at 1.2MHz switching frequency allowing a small-size 1uHinductor for 3.5A fast charging. The current patent-protectedinlegrated sensing technique eliminales exlemal sensing resislor allowing very high charge efficiency, low BOM cost and small footprint. The precharge, fasicharge and termination current accuracy is competitive compared external-resistor-bas ed curent sensing architecture. LP40300 is available in QFN3x3-16 package.

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.
