• Powering LTC6812

    Hi, 
    While analyzing the failure modes of my system that consists of the LTC6812 IC, I am running into a scenario where the path to the V+ pin might break. In this case, can the sense pins (namely C15) provide power to the 6812 IC? 

    I have done some testing…

  • LTC6812 Measuring GPIO pins while discharge transistors are enabled

    Hello, 
    While working with the LTC6812, I am unable to read the voltage across the GPIO pins accurately when the discharge transistors are enabled. Here are the details of what I am trying to achieve:
    1. Read voltage/temp at 2Hz. (GPIO pins are connected…

  • Question about Daisy chain configuration of LTC6812-1

    Hello,

    My customer is reviewing ADI BMS solutions and ask some questions about daisy configuration.

    Please refer Fig.18/Fig.19 in LTC6812-1 datasheet.

    Q1) Would you let me know your opinions about advantages and disadvantages of Capacitive-Coupled Daisy…

  • RE: Questions on BMS LTC6812/3 and active balancer LTC3300 and LT8584

    Regarding number 4:

    The cell voltage and temperature are of asil C FSRs

    For achieving higher asil for temperature measurements it is clear from the safety manual that we can use different thermistor circuits on different non adjacent GPIOs, however for…

  • about the SPI mode of the LTC6812.

    Let me ask you about the SPI mode of the LTC6812.

    According to the data sheet, SPI is in mode 3.

    However, looking at the DC2350AA software program on HP, it runs in mode 0. (When I actually checked the waveform, it was mode 0)

    I recognize that the software…

  • LTC6812断线检测功能

    在调试LTC6812的断线检测功能时,遇到以下问题:

    当只剪断一根测量线的时候,断线检测功能能够准确检测到断线的单体;

    而当同时剪断两根相邻的测量线的时候,却只有一个引脚的电压差超过-400mV;

    当剪断的测量线测量接的时跨接用的铜排时,引脚上的前后压差不小于-400mV;

     

    断开两根以及断开跨接铜排上的检测线时,检测结果与实际情况不相符,请问这个现象是否正常?

  • LTC6812-1 Not responding

    Hello,

    I am having some issues in getting responses from the LTC6812-1 BMS IC. I am operating it in the isoSPI and i am trying to read back the configuration register. But i keep getting 0xFF in my reception buffer. I checked the  section in the data sheet…
