Preliminary Datasheet LP28011 1A Single Chip Li-Ion and Li-Polymer Charger General Description The LP28011 is a complete constant-current / constant-voltage linear charger for single cell lithium-ion battery. Its TDFN-10 package and low external component count make the LP28011 ideally suited for portable applications. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor(RISET). The LP28011 automatically terminates the charge cycle when the charge current drops to 1/10 setting current value after the final float voltage is reached.
