LTC3337: Nanopower primary battery SoH monitor with precision coulomb counter

The LTC3337 is battery-friendly by presenting the battery with a load profile that allows it to deliver its maximum capacity, independent of the actual load.

Key Features and Benefits

  • •  Ultralow quiescent current of 100 nA gives longer battery run times, helpful in remote locations where access is minimal or difficult
  • •  Infinite dynamic range is accurate across all load profiles
  • •  Allows battery to run at maximum capacity by presenting the battery an optimized load profile

Applications

  • •  General purpose: low power primary battery-powered systems (for example, 1× LiSOCl2, 2–3× alkaline)
  • •  Consumer: electronic door locks
  • •  Industrial automation: remote industrial sensors (meters, alarms, etc.), asset trackers

Evaluation Board

The LTC3337 can be evaluated with the DC2973A.
