LTC4069 Standalone 750mA Li-Ion Battery Charger in 2 Ч 2 DFN with NTC Thermistor Input DESCRIPTION
The LTC®4069 is a complete constant-current/constantvoltage linear charger for single-cell lithium-ion batteries.

The 2mm Ч 2mm DFN package and low external component count make the LTC4069 especially well-suited for portable applications. Furthermore, LTC4069 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 LTC4069 automatically enters a low current state, drop
