• RE: LTC6804-2 VOV

    voltage_vov_threshold = 4094 (that it is 8.5V)

    Configuring 4094(0xFFE) into VOV bits in the Configuration register corresponds to configuring an Over Voltage threshold at 6.5504V (=4094*16*100uV)


    Any of you have any clue on this?
  • LTC6804-2, reading first two cells to be 0x00

    Hi, I'm having trouble reading the first two cells of my battery stack, I'm using the LTC6804-2 chip. The issue occurs when the LTC6804-2 is connected in parallel with another microcontroller client on the same SPI bus. However I can read cells…

  • LTC6804-2 STCOMM command

    Hello everyone,

    I have a problem regarding starting the spi communication using the LTC6804-2 as SPI generator. The target is to controll an LTC3300 ic with the "3 wire spi" generated by the GPIO of LTC6804-2.

    I understood that first the GPIO3…

  • LTC6804-2 Parallel 4-Wire SPI Communication Issue, reading back 0xFF

    I am trying to use LTC6804-2 chips to measure and monitor 20 battery cells. So far I have had success using a single LTC6804-2 chip to measure 12 out of 20 of the cells. I am using the 4-wire interface and a digital isolator that has its own isolated ground…

  • RE: LTC6804-2 too much input current

    Yes, thanks for the help.

    I want to monitor just six cells, so I use just one LTC6804-2. Below there is the schematic of which I soldered just: the LTC6804-2, the header connectros for the address and swten (J8 to J12), the BJT with R2 and C2, C5 on the…

  • LTC6804-2 Balancing

    I'm using LTC6804-2 and STM32F405 to monitor 12 cells on SPI cable, and when I used the function LTC6804_wrcfg() to get passive balancing, there doesn't have any balancing signal on slave boards. I found that low PEC cmd[2], cmd[3] and high PEC…

  • LTC6804-2 PEC and voltage reading error

    Hello

    I am designing BMS slave devices based on LTC6804-2. For it's software simulation I'm using PROTEUS software. I am right now trying it for 4S configuration in the simplest circuit diagram.

    I have a problem in reading the voltage of 4 cells…

  • LTC6804-2 cannot communicate after changing the configuration register

    In the test, I used the DRIVE pin to drive the transistor to generate VREG, the WTD pin was left floating, and the SWTEN pin was connected to GND. When the power is just turned on, the DRIVE pin always has 5.6V output, and the IC never sleeps. I used…

  • Active cell balancing using the DC2100B-D (LTC3300-1/LTC6804-2) with arduino

    I have two question regarding the DC2100B-D which is a slave board consist of LTC 3300-1 and LTC 6804-2. It doesn't contain the Micro controller and the LTC6820. I am planning to use the Arduino and LTC6802 shield for Arduino together.
