• 8-cell LiFePO4 charger with LTC4162-F and LTC6803-4: Battery not detected


    I'm designing a laptop that has the unique feature of using LiFePO4 batteries (8x 18650 cells in series). To charge them, I chose the LTC4162-F charger coupled with a LTC6803-4 cell stack monitor. Both are watched/controlled by a NXP LPC11U24 MCU…

  • LTC4162 for charging LiFePO4 and backup with PowerPath and I2C Telemetry

    We have a request for LiFePO4 Step-Down Battery Charger.

    For 4S1P application,

    Vin : 9V~36V


    18V->LTC4162-F->Charge LiFePO4 and backup with PowerPath and I2C Telemetry

    Do we have LTC4162-F EVB or Reference Circuits inclu…

  • RE: Problem with LTC4015



    I actually think your components sound fine since you were charging up to 8A. At least, so far, I don't have a reason to believe there is a problem with your components.


    This sounds like a battery hot-swapping and inrush issue, which…

  • RE: Battery Charge Controller for Solar Power

    Hi Pauline,

    Yes, LTC4162 is probably the best choice for your application if your desired charge current is 3.2A or less. Otherwise, you might consider LTC4015.

    The suffix to the LTC4162 part number denotes the battery chemistry type that it supports…

  • LTC4162-L fixed register list on fix version ( LTC4162-L42 ).

                    For LTC4162-L (Lithium Ion) version in datasheet its not clear which register are fixed in fix version ( LTC4162-L42 ).
    Please tell me register address which can not be modified/write in fix version.

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

    Yes, it will work with a LiPo battery. Refer to the -L datasheet for that. The LiFePO4 variants are detailed in the -F datasheet.

    As for protection, it depends what you mean. One thing that the LTC4162 does not do is low-battery disconnection from the…

  • RE: LTC4162-L


    The folders refer to each LTC4162 variant.

    If you are using LTC4162-LAD, you would use the LTC4162-LAD folder. If you are using LTC4162-L41, you would use the LTC4162-L41 folder, etc.

    Note that LTC4162-L is not an orderable part number. Refer to…

    Data gathered by LTC4162 is enough to monitor the battery 


  • RE: LTC4162-SAD Demo Circuit 2038A Programming problem

    Hi Zack

    Firstly, thanks for picking this up.

    So, If I am understanding this correctly, I have an LTC4162-SAD PCB, so therefore to modify the onboard firmware I should use the Mzero  project (located in the SDK an LTC4162>c_code>examples>dc2038a>THC4162…
