Product Introduction

Overview

The LTC3337ERC#TRPBF, produced by Analog Devices Inc., is a primary battery state of health (SOH) monitor equipped with a built-in precision coulomb counter. This device is designed to be placed in series with a primary battery, ensuring minimal associated series voltage drop. It provides accurate, real-time readings of battery cell discharge, voltage, impedance, and temperature. The LTC3337 integrates an infinite dynamic range coulomb counter that tallies all accumulated battery discharge and stores it in an internal register accessible via an I2C interface. A programmable discharge alarm threshold based on the state of charge (SOC) generates an interrupt at the IRQ pin when reached.
