• RE: LTC4162-L

    Hi Bob,

    Here's a possible solution without a microcontroller. This uses an ultra-low-power comparator so it does not discharge the battery much. I had drawn this for a different IC but the principle still applies, you can use an N-channel FET on the low…

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

    Hi,
                    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.

  • 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…

  • LTC4162-L

    I'm trying to create a stand alone battery charger for a single 18650 battery.

    For this I created the Schematics and PCB found here.

    But during the charging only charges with <1A (differential measured over the sense resistor <20mV/20mohm) instead…

  • LTC4162-L stuck on CC_CV_CHARGE

    Hello,

    we are working on a prototype board which provide the LTC4162_EUFD_LAD battery charger.
    according to the project specifications, our product will work constantly powered by an external source and, in case of lack of power, the internal battery will…

  • LTC4162-L charging issue

    Hello,

    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…

  • 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…

  • LTC4162-L Telemetry Data Question

    Hello,

    I am curious about the quality of the data from the LTC4162-L via the I2C channel. Is there enough information received to adequately fuel-gauge a battery or is an additional IC recommended? If another IC is needed, can the sense resistor be shared…

  • RE: LTC4162-S (DEMO DC2038A) Simulated Temperature Adjustment

    Hi Michael,

    That is supported actually, but you are using LTC4162-S which does not have a JEITA function. If you were using LTC4162-L or LTC4162-F you would see the JEITA tab. Otherwise, it is hidden (the demo manual does mention that it is hidden for…

  • 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…
