Preliminary Datasheet LP28056 1.2A Single-chip Li-ion and Li-POL Charge with OVP General Description The LP28056 is a complete constant-current/ constantvoltage linear charger for single cell lithium-ion batteries. Its TDFN-10 package and low external component count make the LP28056 ideally suited for portable applications. Furthermore, the LP28056 is specifically designed to work within USB power specifications. Its have a over voltage protection in input with 6.5V and support over zero voltages of battery can charge enable. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature.
