General Description
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.
