Product Summary

The LP4060B5F is a complete constant-current/constant voltage linear charger for single cell lithium-ion batteries. Its ThinSOT package and low external component count make the LP4060B5F ideally suited for portable applications. Furthermore, the LP4060B5F 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.
