DESCRIPTIO

The DC101 board is a standalone Smart Battery charger

that receives Charging Voltage(), Charging Current() and

AlarmWarning() commands from the Smart Battery via

the System Management Bus (SMBus) and sets charging

current and voltage accordingly. The charger continu-

ously monitors the built-in thermistor in the battery. The

thermistor information is used by the software to inhibit

charging at temperature extremes and to set charging

strategy for different battery chemistries.
