• LTC4079 Linear Battery Charger

    Hi,

    I am using LTC4079 in the battery backup system of my design to charge Li-Ion batteries. The input and output voltages of LTC4079 are 24 V and 4.2 V, respectively. If there are fluctuations in the input voltage, let's say it drops down to 16V from…

  • RE: LTC4079 input resistor

    Hello,

    The input current is not a constant value, which is why it can't be specified in the datasheet. For a linear charger, the input current will be equal to the output current. So, if you want to reduce power dissipation, all you need to do is reduce…

  • RE: Setting battery temperature qualified charging LTC4079.

    Hello,

    Here's what you need to know:

    Those are the thresholds as a ratio of VNTC to VNTCBIAS. The rest of the calculation comes down to choosing your thermistor and maybe tweaking the network with series / parallel resistance.

    I've attached an Excel…

  • RE: LTC4060 slow charge

    Hello,

    In general, slow charging NiCd cells makes termination a little more difficult.

    You are correct that –∆V termination is less reliable when charging slowly. Unfortunately, so is temperature-based termination. Your concern with –∆V termination may…
