Overview
Standalone Linear Li-Ion Battery Charger with Thermal Regulation CE3150B Series „ INTRODUCTION: The CE3150B is a complete constant-current/ constant –voltage linear charger for single cell lithium-ion batteries.
Its SOT package and low external component count make the CE3150B ideally suited for space limited portable applications.
Furthermore, the CE3150B 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.
The charge voltage is fixed at VFLOAT, and the charge current can be programmed externally with a single resistor connectd between PROG pin and GND.
The CE3150B automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
When the input supp...
