• LTC4071 in Parallel

    When running multiple LTC4071's in parallel for multiple cells does each LTC4071 need its own current limiting resistor? It seems when they are paralleled that each resistor ends up parallel as well. How do I achieve proper current limiting when running…

  • Charging and protection for a LIR2032 cell: LTC4071

    Hi EZ!

    I'm new to Li-Ion battery design, so please don't judge if I make stupid mistakes. In our IoT solution we use a LIR2032 Li-Ion cell. Here is some information from it's datasheet:

    Nominal Voltage: 3.6V
    Nominal Capacity: 35 mAh
    Maximum…

  • Solar powered lithium charger with LTC3105 & LTC4071

    I would like to implement the lithium battery charger given at https://www.analog.com/en/design-center/reference-designs/circuit-collections/ltc3105-ltc4071-2-cell-solar-panel-li-ion-battery-charger.html#cc-overview.  Battery being charged is Li-Ion 3.7V…

  • LTC4071 - VCC drooping to 0V after disconnecting Solar Panel

    Hello,

    I am using LTC4071 to charge LiPo (3.7 1200ma) from Solar Panel. I have a custom made PCB for this. The connection on PCB is as follows:

    NTCBAIS - Floating

    NTC - connected to VCC

    ADJ - Floating

    LBSEL - connected to VCC

    BAT - connected to…

  • RE: Flexible power harvesting Chip

    Hi kaveh14934,

    Could you clarify what do you mean by flexible? Yes, the LTC4071 can be used for energy harvesting (see Figure 7 on the datasheet). 

    Here are other parts that can be used of energy harvesting: Selection Table for Energy Harvesting | Parametric…

  • RE: Battery Management, LED Driver ICs

    Hi Rob,

         Now I understand your application a little better.  With your solar panel connected directly to the Li-ion cell, the latter loads down the nominal 6V panel's output to about 4V, where it can supply some decent current.  You only need the battery…
