Charger Controller  
FEATURES  
DESCRIPTION  
The LTC®4101 Smart Battery Charger is a single chip  
chargingsolutionthatdramaticallysimplifiesconstruction  
of an SBS compliant system. The LTC4101 implements  
a Level 2 charger function whereby the charger can be  
programmed by the battery or by the host. A SafetySignal  
onthebatterybeingchargedismonitoredfortemperature,  
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).

User-Selectable Overvoltage and Overcurrent Limits  
High Noise Immunity SafetySignal Sensor  
Available in a 24-Pin SSOP Package  
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  
whensimultaneouslysupplyingloadcurrentandcharging  
current. When supplying system load current, charg-  
ing current is automatically reduced to prevent adapter  
overload.
