Lithium Battery Charger using BQ24103

The BQ24013 is a simple-to-use charge controller suitable for use with lithium-ion and lithium-polymer batteries. A major advantage it has is that it includes integrated power MOSFETs capable of working with charge currents of up to 2 A. Its switching frequency is high, at 1.1 MHz, and so only a small external coil is needed. In comparison to linear charging circuits the switching topology offers a much higher degree of efficiency.
