The LTC1760 Smart Battery System Manager is a highly-integrated SMBus Level 3 battery charger and selector intended for products using dual smart batteries. Three SMBus interfaces allow the LTC1760 to servo to the internal voltage and currents measured by the batteries while allowing an SMBus Host device to monitor either battery’s status. Charging accuracy is determined by the battery’s internal voltage and current measurements, typically better than ±0.2%.A proprietary PowerPath architecture supports simultaneous charging or discharging of both batteries. Typical battery run times are extended by up to 10%, while charging times are reduced by up to 50%. The LTC1760 automatically switches between power sources in less than 10μs to prevent power interruption upon battery or wall adapter removal.The LTC1760 implements all elements of a version 1.1 “Smart Battery System Manager” except for the generation of composite battery information. An internal multiplexer cleanly switches the SMBus Host to either of the two attached Smart Batteries without generating partial messages to batteries or SMBus Host. Thermistors on both batteries are automatically monitored for temperature and disconnection information (SafetySignal).
