The LM3658 is a single chip charger IC designed for handheld
applications. It can safely charge and maintain a single cell
Li-Ion/Polymer battery operating from an AC wall adapter or
USB power source. Input power source selection of USB/AC
is automatic. With both power sources present, the AC power
source has priority. Charge current is programmed through
an external resistor when operating from an AC wall adapter
allowing charge currents from 50 mA to 1000 mA. When the
battery is charged using USB power, charge currents of 100
mA or 500 mA are pin-selectable. The termination voltage is
controlled to within ±0.35% of 4.2V.
