Overview

Preliminary Datasheet LP28052A 10V/1.
2A Single-chip Li-ion and Li-POL Charge General Description The LP28052A 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 LP28052A ideally suited for portable applications.
Furthermore, the LP28052A 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.
The charge voltage is fixed at 4.
2V, and the charge current can be ISET rammed externally with a single resistor.
The LP28052A automatically terminates the charge cycle when the charge current drops to 1/10th the ISET ram...
