Product Overview

The LTC4061EDD#PBF is a standalone Linear Charger for single-cell Li-ion batteries. This full-featured flexible charger is capable of operating within USB power specifications. Both programmable time and programmable current based termination schemes are available. Furthermore, the CHRG open-drain status pin can be programmed to indicate the battery charge state according to the needs of the application. Additional safety features designed to maximize battery lifetime and reliability include NTC battery temperature sensing and the SmartStart charging algorithm. No external sense resistor or external blocking diode is required for charging due to the internal MOSFET architecture. Internal thermal feedback regulates the charge current to maintain a constant die temperature during high power operation or high ambient temperature conditions. The charge current is programmed with an external resistor.
  • Charges single-cell Li-ion batteries directly from USB port
  • Preset charge voltage with ±0.35% accuracy
  • Thermistor input for temperature qualified charging
  • Input supply present logic output
  • Thermal regulation maximizes charge rate without risk of overheating
  • Programmable charge current detection/termination
  • Programmable charge termination timer
  • Smart pulsing error
  • SmartStart™ prolongs battery life
  • 20µA Charger quiescent current in shutdown
