The LP4032 is a standalone 1-cell switching battery charger providing up to 2A charge current to the battery from 4.1V to 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 resistor connected from VSET to GND. The LP4032 operates at 1.2MHz switching frequency allowing a small-size 1uH inductor for 2A fast charging. The patent-protected integrated current sensing and control technique eliminates external sensing resistor and allows very high charge efficiency, low BOM cost and very small footprint. The LP4032 charge current and end-of--charge (EOC) current accuracy is competitive compared to external-resistor-based current sensing and control architecture The LP4032 is available in DFN3*3-10 package.
