LTC1734
The LTC1734 is a low cost, single cell Li-Ion battery charger with constant voltage and constant current control. The small quantity and low cost of the external components results in a very low overall system cost, and with the IC’s 6-pin SOT-23 package, provides a compact design solution. Previous products usually required an external current sensing resistor and blocking diode, but these functions are now provided within the LTC1734. Other features ...
