ANALOG DEVICES INC. LTC3337 Primary Battery State of Health Monitor
Analog Devices Inc. LTC3337 Primary Battery State of Health Monitor provides accurate, real-time readings of battery cell discharge, voltage, impedance, and temperature with a built-in precision coulomb counter.
It 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 via an I2C interface.
To accommodate a wide range of primary battery inputs, the peak input current limit is pin selectable from 5mA to 100mA.
Coulombs can be calculated for either the BAT_IN or BAT_OUT pin, determined by the AVCC pin connection. A BAL pin is provided for applications utilizing the option of a stack of two supercapacitors at the output.
The LTC3337 is offered in a 12-lead LFCSP package as well-suited for lower power primary battery powered systems, remote industrial sensors, asset tracker, electronic door locks, and more.
