DESCRIPTION
The LTC®1732-8.4 is a complete constant-current/constant-voltage linear charge controller for lithium-ion (Li-Ion) batteries. Nickel-cadmium (NiCd) and nickel metal hydride (NiMH) batteries can also be charged with constant current using external termination. Charge current can be programmed with ±7% accuracy using external sense and program resistors. An internal resistor divider and precision reference set the final float voltage with ±1% accuracy.

FEATURES
■ Complete Linear Charger Controller for 2-Cell Lithium-Ion Batteries
■ Preset Charge Voltage with ±1% Accuracy
■ Programmable Charge Current
■ C/10 Charge Current Detection Output
■ Programmable Charge Termination Timer
■ Small, Thin 10-Pin MSOP Package
■ Input Supply (Wall Adapter) Detection Output
■ 8.8V to 12V Input Voltage Range
■ Automatic Sleep Mode When Input Supply Is Removed (Only 10µA Battery Drain)
■ Automatic Trickle Charging of Low Voltage Cells
■ Programmable for Constant-Current-Only Mode
■ Battery Insertion Detect and Automatic Charging of Low-Battery
■ Automatic Battery Recharge
