• LTC2944 Gauge IC correct settings

    Hello

    I use the Linduino with the LTC2944 Gauge IC.
    Now i connected all but gives not good results.
    What for parameters i need to write in the LTC2944 for my Battery (5 Cells Serial 18.5V 3000mAh) ?
    My charger brings 1300mAh but the Scan mode show always…

  • LTC2944 State Of Charge

    Hi,

    I have a few questions regarding the charge and capacity calculations. I read the datasheet, but I am missing something.

    How do I calculate the value shown in the ACR register? Register C/D reads: 7B72, but the gas gauge shows -216.58 mAH

    I have used…

  • LTC2944 With Arduino Uno not working

    Hello,

    I am currently having issues communicating with the LTC2944 using an Arduino Uno over I2C. I have the DC1812A demo board for easy prototyping and everything works perfectly using a Linduino One. I currently have the Arduino Uno connected to the…

  • LTC2944 Sense + or Senso - Damage?

    Hi,
    
    I am using the LTC2944 chip to measure battery voltage. But the Sense + or Sense- pin sometimes broken.
    Battery voltage is 48V and diodes are also applied. The circuit is shown below.

    I only want to use this chip for battery voltage measurements.…

  • LTC2944 abnormal behaviour : wrong and unexpected UVLO.

    Hi,
    We are using the LTC2944 inside a battery gauge application. Everything worked well during development stages. However we have more and more chips that behave in an abnormal way : as soon as a little current  goes through the shunt resistor (2mOhms…

  • Calculating Rsense Resistor Value in LTC2944

    Hello,

    I have a Lithium-ion battery, which consists of 14 cells each cell being 4.2V and 2900mAH connected in series.

    The maximum charge input is 58.5 volts and 10A.

    Therefore, I want to choose Rsense resistor value for 10A input. According to the formula…

  • LTC2944 About Accumulated Charge Register - Partially Solved

    I have the following questions about the ACR which are not addressed (or clear) in the section starting on page 11  answered some myself

    1. Is the units of the ACR in mAhr?
