Description

The LTC®4071 allows simple charging of Li-Ion/Polymer batteries from very low current, intermittent or continuous charging sources. A near-zero current low battery latching disconnect function protects even the lowest capacity batteries from deep discharge and potentially irreparable damage.

Key Features

  • Low Operating Current (550nA)
  • Near Zero Current (<0.1nA) Low Battery Disconnect Function to Protect Batteries from Over-Discharge
  • Pin Selectable Low Battery Disconnect Level: 2.7V or 3.2V n 1% Float Voltage Accuracy Over Temperature n 50mA Maximum Internal Shunt Current
  • Pin Selectable Float Voltage Options: 4.0V, 4.1V, 4.2V
  • Ultralow Power Pulsed NTC Float Conditioning for Li-Ion/Polymer Protection
  • Suitable for Intermittent, Continuous and Very Low Power Charging Sources
  • High Battery Status Output
  • Thermally Enhanced, Low Profile (0.75mm) 8-Lead (2mm × 3mm) DFN and MSOP Packages
