LTC4100 Smart Battery Charger Controller DESCRIPTIO
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 chemistryspecific limits for improved system safety and reliability. Limits are programmable by two external resistors. Additionally, the maximum average current from the AC adapter is programmable to avo
