Circuit Charges Lithium-Ion Cells


Posted on Dec 1, 2012

The charger is built around a single LTC®1541, which contains a voltage reference, op amp and comparator. The high accuracy voltage reference (±0.4%) regulates the battery float voltage to ±1.2%, as required by most Lithium-Ion battery manufacturers.



A single Lithium-Ion cell is often the battery of choice for portable equipment because of its high energy density. The 3V to 4.1V provided by a Lithium-Ion cell is also a good match for modern low voltage circuits, often simplifying the power supply.
