Learn more about how the Analog Devices' LTC3337 is the lowest IQ SoH (state of health) monitor and precision coulomb counter with infinite dynamic range.
The LTC3337 is designed to be placed in series with a primary battery with minimal associated series voltage drop. The patented infinite dynamic range coulomb counter tallies all accumulated battery discharge and stores it in an internal register accessible through an I2C interface. The LTC3337 is accurate across all load profiles and measures all important SoH variables (Q, V, Z, T), and presents the battery with a load profile that allows it to deliver its maximum capacity, independent of the actual load.
