LTC3337ERC#TRMPBF
The LTC3337 is the lowest IQ SoH (state of health) monitor and coulomb counter with infinite dynamic range. It is accurate across all load profiles and measures all important state of health variables (Q, V, Z, T)
Analog DevicesLTC3337: 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.
