Datasheet Summary
Preliminary Datasheet LP28021
1.0A Single-chip Li-ion and Li-POL Charger with OVP Protection
General Description
The LP28021/A is a plete constant-current/ constant voltage linear charger for single cell lithium-ion batteries. Its TDFN-10 package and low external ponent count make the LP28021/A ideally suited for portable applications. 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. The charge voltage is fixed at 4.2V/4.35V, and the charge current can be rammed externally with a single...
