Datasheet Summary
Preliminary Datasheet LP4055
800mA Linear Li-Ion Battery Charger with Protection of Reverse Connection of Battery
General Description
The LP4055 is a plete constant-current/constant- voltage linear charger for single cell lithium-ion batteries. Its SOT23-5 package and low external ponent count make the LP4055 ideally suited for portable applications. Furthermore, the LP4055 is specifically designed to work within USB power specifications. 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....
