Product Overview

The LTC4065EDC-4.4#TRMPBF is a complete constant-current/constant-voltage Linear Charger for high capacity single-cell Li-ion batteries with a 4.4V float voltage. It is specifically designed to work within USB power specifications. The CHRG pin indicates when charge current has dropped to ten percent of its programmed value (C/10). An internal timer terminates charging according to battery manufacturer specifications. No external sense resistor or blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates charge current to limit the die temperature during high power operation or high ambient temperature conditions. When the input supply (wall adapter or USB supply) is removed, the LTC4065-4.4 automatically enters a low current state, dropping battery drain current to less than 1µA. With power applied, it can be put into shutdown mode, reducing the supply current to less than 20µA.
  • C/10 charge current detection output

  • Charge current monitor output for gas gauging
  • Automatic recharge
  • Charges single-cell Li-ion batteries directly from USB port
  • 20µA Supply current in shutdown mode
  • Soft-start limits inrush current
