• LTC4162-L charging issue


    Please help me as I'm stuck!

    I use LTC4162-L to charge a lithium battery and it works great!. I had a few prototype boards and every time I solder it myself. I've been having issues with the latest boards and the design and layout is the same…

  • LTC4162-L

    I am going to use LTC4162-L battery charger for my project.

    For reference, I downloaded "LTC4162 Evaluation Software" from site.

    In "LTC4162-SDK", it contains so many folders with name "LTC4162-xx" .

    Please let me know to…

  • RE: LTC4162-L Powerpath

    Hi Erik,

    You can generally consider it an ideal diode-OR. It will select the higher of the two voltages. In most applications, that means it will select VIN when VIN is present and the battery when VIN is not present.

    If you always want the battery voltage…

    Hello, Mr.Zack.

    I am devemin from Japan.

    I try to make 18650-charger too.

    I asked local agency to get demo's design & PCB sample layout files in Japan, but they said that DC2038 is until not release, so I can't get these files. 

    Can you…

  • LTC4162-L Battery Charger IC with MPPT

    Hello, I have a question.

    I'am designing battery charging circuit with LTC4162-L.

    The block diagram is below,

    There are three solar panels with blocking diode, 3 LTC4162-L circuit, battery management system and 2S4P li-poly battery pack.

    I just tied…

  • RE: LTC4162 EVB and Design Files

    Any updates on when the LTC4162 evaluation board will be available? We are looking to incorporate the LTC4162-L, but it would be nice to get an eval board to do some testing before we implement it in our project.

  • LTC4162-L battery detection issue

    I use LTC4162-L but it don't work, the module is stuck in battery detection test.

    Some how, from time to time it is unstuck from battery detection test to cc_cv_charge, vin_uvcl  and no-rt. So it don't charge my battery as well.
    I read on…
  • LTC4162-L as a standalone charger.

    Hi, I have a question. Does the LTC4162-L work as a standalone unit, or does it require to be programmed? Does it have some sort of default programming built-in? If I just leave SCL and SDA pins high (Via pull-up resistors tied to INTVcc), will the chip…

  • LTC4162-L recommend DVcc connection

    What is the recommendation for DVcc.

    Can I leave this unpowered?

    The Data Sheet states that SCL/SDA must be high when the bus is npt in use.

    But a post on the forum suggests they can be left floating.

    Can they be pulled to DVcc and DVcc be powered down…

  • RE: Solar panel charger that works without a battery or discharged battery

    Hi Emilija,

    I might actually recommend LTC4162-L. It has a dynamic tracking MPPT algorithm that will regulate your solar panel at the max power point at any illumination level. The charge current goes up to 3.2A max, so if that works for you then it may…
