• LTC4162-F battery boost capable?

    Hello,

    I'm in a need of battery management IC with telemetry, that can support 12V output voltage and is rated for 2A output current. The backup is provided by 1 cell LiFePO4 cell, so the IC needs to provide boosted battery output. In current device,…

  • RE: LTC4162-F charging issue at high currents

    Hi GeoffreyJ,

    Hope you are doing well.

    It may be possible that a poor layout can be a factor on your problem especially when you are using only 2 layers. Is your design based on the demo board of the LTC4162-F? If not, I suggest first trying your application…

  • LTC4162-F does not activate ship mode

    Hi,

    Somehow I can't get the ship-mode activated. Vin = 12V and battery = 2S LiFePo4. 
    What I can see with a protocol analyzer looks goodand when I read from the chip I get correct answers.So I2C works correctly.
    I've monitored VCC2P5 but it stays high…

  • LTC4162-F production PCB review request

    Hi,

    Can I please request a review of a 4162-F PCB we are hoping to put into production?

    I have DM'd the files to Zack and can send them anywhere else that is required.

    Thanks in advance,

  • LTC4162-F MPPT input stability

    Hi I've been testing the LTC4162-F Using the DC2038A -N demo board. The 4162 is charging a LifeP04 battery. Vin is connected to a PV simulator. The Simulator is configured as follows;

    VMP = 19.8V

    IMP = 6.5A

    As you can see in the above plot the battery…

  • LTC4162-F custom PCB issue causing continuous battery detection and a failure to charge

    Hi,

    I have an issue where I have implemented a few protection measures in my latest PCB and it appears that I have somehow affected the battery charge circuitry. As it stands, I am unable to find the issue, which results in the battery never being charged…

  • LTC4162-F Voltage Adjustment Issue

    Hi,

    I am using the LTC4162-FAD in a solar powered battery charger that I am working on but I have encountered an issue with changing the "vcharge_setting" on this supposedly adjustable chip.

    When the LTC4162 is first powered up my I2C master…

  • LTC4162-F I2C issue

    HI all,

    I have a new board design that I am vetting at the moment and can not get I2c to work. I am using an RPi as the master and have other slaves working on the bus without issue.

    The LTC4162 appears to be working fine in that it charges the battery…

  • LTC4162-F , 无法充电,充电如何开启!

    LTC4162-F , 如何开启充电动作!

    LTC4162-F , 默认设置,电池8节,电压26.6V, 输入电压30V。

    电池电压,输入电压,读取数值正确。NTC电阻采用10K电阻。

    问题:1.  充电无动作,无充电电流,如何设置,开启充电动作。读取寄存器0x34=256,0x35=0x36=0x37=0x38=0, 0x39=0X3E67,0x43=0x0X8428。

                2.  当无输入电压时,为何读取电池电压、电池电流数值也为0.   同时0x43=0x420;
