TYPICAL APPLICATION
DESCRIPTION
Smart Battery
Charger Controller
The LTC®4100 Smart Battery Charger is a single chip
charging solution that dramatically simplifies construction
of an SBS compliant system. The LTC4100 implements
a Level 2 charger function whereby the charger can be
programmed by the battery or by the host. A SafetySignal
on the battery being charged is monitored for temperature,
connectivity and battery type information. The SMBus
interface remains alive when the AC power adapter is
removed and responds to all SMBus activity directed to
it, including SafetySignal status (via the ChargerStatus
command). The charger also provides an interrupt to the
host whenever a status change is detected (e.g., battery
removal, AC adapter connection).
Charging current and voltage are restricted to chemistry-
specific limits for improved system safety and reliability.
Limits are programmable by two external resistors. Ad-
ditionally, the maximum average current from the AC
adapter is programmable to avoid overloading the adapter
when simultaneously supplying load current and charging
current. When supplying system load current, charg-
ing current is automatically reduced to prevent adapter
overload.
