s Complete Linear Charger Controller for 1-Cell Lithium-Ion Batteries s 1% Voltage Accuracy s Programmable Charge Current s C/10 Charge Current Detection Output s Programmable Charge Termination Timer s Space Saving 8-Pin MSOP Package s Automatic Sleep Mode When Input Supply is Removed (7µA Battery Drain) s Automatic Trickle Charging of Low Voltage Cells s Programmable for Constant-Current-Only Mode U APPLICATIO S s Cellular Phones s Handheld Computers s Charging Docks and Cradles s Programmable Current Source LTC1731-4.1/LTC1731-4.2 Single Cell Lithium-Ion Linear Battery Charger Controllers DESCRIPTIO The LTC®1731 is a complete constant-current/constantvoltage linear charger controller for single cell lithium-ion batteries. Nickel-cadmium (NiCd) and nickel-metal-hydride (NiMH) batteries can also be charged with constant current using external termination. The external sense resistor sets the charge current with 5% accuracy. An internal resistor divider and precision reference set the final float potential with ±1% accuracy.
