• QuikEvel Software detects LTC6811-2 Demo board but does not work


    I use the Linduino One development board with the DC590B sketch loaded, connected to the LTC6811-2 demo board as described in this Manuel https://www.analog.com/media/en/technical-documentation/user-guides/DC2260AF.PDF

    After opening the QuikEval software…

  • LTC6811-2 connect arduino

    Hello everyone. I am working on a battery manangment system for electric vehicles. I am thinking of using the ltc6811-2 integrated for this system. I will use Arduino to control the system. I have Arduino codes of dc2259a demo board. Actually these codes…

  • RE: LTC6811-2 unable to communicate over isoSPI

    Unfortunately the log is showing no communication from the IC, so you will need to check the hardware setup.

    What clock speed is being used for the communication?

    What address is the LTC6811-2 configured for (which of pins A0-A3 are tied to V-/Vreg)


  • RE: LTC6811-2 ADAX error after setting cfgr register

    I am not sure if i understood the question correctly. What i understood from Google translate is after you set CFGR with DCC bits. your measurement of temperature from GPIO changes from 25C to 79C?

    Is this what you meant? 

    Can you please share the raw…

  • LTC6811-2 unable to sample NTC thermistors connected to GPIO 1 and 2


    Connected two NTC thermistors to the GPIO 1 and 2. When start writing configuration registers with respective bits set for GPIO 1 and 2 noticed that they have been reset upon writing configuration in case if NTC thermistors are connected. What…

  • LTC6811-2 (4-Wire SPI)


    I’m considering using two of the LTC6811-2 devices using a 4-wire SPI bus approach.

    The issue that I’m concerned about is that technically the 1st 6811 device will be connected to the first 12-Cells with a voltage range from up to 50V…

  • DRIVE not responding to toggle on CSB. LTC6811-2 SPI communication.

    We are testing a prototype BMS with 12 cells, and are having communication issues it seams. When we toggle CSB we excpect 5V on the DRIVE pin, but we just measure 2.14V with no change instead. We have tried testing with and without a pullup resistor but…

  • 使用LTC6811-2做电池管理AD采集,用SPI通信4线,LTC6811-2的SPI如何设置?有适合LTC6811-2的SPI配置库函数吗?官网提供的LTC6811函数里没有SPI配置







  • LTC6811-2: Cell measurement always returns 6.5535


    I made a custom PCB with an ATmega328P and a LTC6811-2 chip.
    The LTC6811-2 is configured to work in 4-Wire SPI mode.
    I uploaded the DC2259.ino file to the MCU. After powering the PCB I receive the menu interface over the serial interface as expected…
