    Thread Summary
    
                The user is considering using the MAX17048 fuel gauge IC for a new design with a 500 mAh, 3.7 V lithium-ion battery. The final answer confirms that the MAX17048 is still recommended for new designs and that Analog Devices provides support for it. The datasheet is up to Rev 7, last updated in 2016, and any known issues are reflected in the datasheet updates.

    Hello Team,
    

    I am planning to use the MAX17048 fuel gauge IC in my upcoming design. However, I have come across multiple discussions on forums (including Stack Exchange and Analog Devices community) highlighting issues related to this chip.
    

    Additionally, I noticed that official support responses seem very limited or sometimes absent.
    

    My Battery:
    

    www.reichelt.com/.../lithium-ion_battery_soldered_333278_500_mah_3_7_v-373542
    

    Before I proceed, I would like to clarify:
    

      

    1. Is MAX17048 still recommended for new designs?
      2. 

    2. Will I receive adequate support from Analog Devices if I encounter issues during development or production?
      3. 

    3. Are there any known limitations or errata that I should be aware of?
      4. 

    4. If this part is not recommended, could you suggest an alternative IC with similar functionality?
      5. 

    

    Your guidance will help me make an informed decision for my project.
    

    Thank you in advance!
    

    HARI

      1. Is MAX17048 still recommended for new designs? Yes
        2. 

      

      MaX17048 is officially designated as recommended for new designs. The other classifications we have are Production (recommended for new designs but there are probably better alternatives available)  and Not Recommended for New Designs
      

      

        

      1. Will I receive adequate support from Analog Devices if I encounter issues during development or production?
        2. 

      

      We provide support for all devices that are designated as "Recommended for New Designs" and "Production"
      

       
      

        

      1. Are there any known limitations or errata that I should be aware of?
        2. 

      

      We mostly do not publish errata documents. If we find a mistake in the datasheet or if the device is found to have a shortcoming, we will update the datasheet to reflect this. The datasheet is up to Rev 7 and the last edit was in 2016.

        Hi Enash,
        

        Thank you. I will go ahead with MAX17048.
