The IA1401 is a complete constant current/constant voltage linear charger for single cell lithium-ion batteries. Its package and low external component count make the IA1401 ideally suited for portable applications. Furthermore, the IA1401 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. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The IA1401 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
Features:
Programmable Charge Current Up to 500mA
No MOSFET, Sense Resistor or Blocking Diode Required
Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize Charge Rate
