• LTC4015 Qcount

    Hi,

    We are using LTC4015 for charging 2S4P Li-ion battery. The battery capacity is 7.4V/10.4Ah. We have s single input supply which can provide either 11V or 15V to the charger. When 11V is applied we are charging the battery with 900mA current and when…

  • LTC4015 precharge

    Dear Team,

    Im charging a battery with LTC4015 (2 Li-Ion x 4.2V). Im testing the condition when battery is discharged less than 2.4V. I see that every 30 seconds charger tries to run the charge (I see ripples on the oscilloscope) but after some time they…

  • LTC4015 gate driver

    Hello. I'm designing high current charger for lead acid battery, two 12 V in series (150 Ah). Maximum charge current must be 10A.

    In my design are used MOS FET BSZ028N04LS (Vds=40V, Id= 40A, Rds=2.8mOhm). For have to more safe LTC4015, is it possible…

  • LTC4015 arduino code

    Hi, 

    I have bought the demo board of ltc4015 (DC2039A). I can communicate with the arduino (get battery info etc...).

    But unfortunately I am unable to set the Icharge and Vcharge. I think there is just some problem in my code. 

    void set_charge_current(float…

  • LTC4015 Charge voltage

    Hello ADI experts,

    I want to charge 8 series Li ion battery pack with LTC4015. I want to use 8 series Li ion battery so I need to 33.6 Volts  (When 18650 Li ion batteries are charged, their voltage can reach to 4.2V, 8x4.2V=33.6V)  but in the datasheet…

  • LTC4015 ICHARGE_TARGET and VCHARGE_SETTING not working after power cycle

    Hi,

    Everything seems to be working well with our LTC4015 based LiFePO4 battery charger board with the exception of the charge current and vcharge aren't consistent after the power cycles.  I can read and write the value 21(decimal) via I2C to register…

  • LTC4015 I2C Issue

    In a valid system state where there is no input power to the BMS AND no battery, the I2C bus appears to be pulled down by the LTC4015, affecting communication to other I2C devices existing on the same I2C bus. It is desirable to be able to communicate…

  • LTC4015 MOSFET selection

    Hello,

    We are designing a product to charge 2x28Ah 12V lead acid batteries in paralell using the LTC4015.

    We have made a test board with the reference components from the outlays in the datasheet, but one of the FDMC8030 transistors was destroyed, I…

  • IIN_LIMIT_ACTIVE problem on LTC4015

    I’m designing a 6s li-po battery charger board using LTC4015. The ICHARGE_TARGET was set to be 8A. However, the charge current (IBAT) was about only 1A using 30V power supply. The charge status showed IIN_LIMIT_ACTIVE. Not sure why the charge current…

  • LTC4015 INTVCC failure

    Dear all users and EZ team:

    I am using a custom design based on the LTC4015 eval board schematic for LiFePo4 8S 50A battery. The main changes are: higer current INFET, higher current OUTFET, lower RSNSI (1mOhm) and lower RSNSB (0.5mOhm). I am able to…
