• RE: (AD8280)To use at 12V Li.-ion .

    Hi Kawa-san,

    Unfortunately, the AD8280 temperature range can not be extended to 125C without a significant amount of re-qualification. The AD8280 is a good candidate for applications requiring a hardware monitor to check 4 x 3V cells for over an under…

  • AD8280 self-test content

    Hi,

     

    We intend to use the AD8280 safety environment. The content description of the self test is rather slight in the datasheet.

    As the diagnostic is a very important part of our project, we need to know what is precisely performed in the self-test…

  • RE: AD8280:What is the LDO min overhead voltage

    Hi Luke,

    I already emailed the product owner of the AD8280 regarding your question. I will get back to you as soon as I hear anything.

    Best regards,

    Emman

  • AD8280: (Apparent) inconsistencies between AbsMax and data sheet

    Dear all,

    We have selected the AD8280 as a secondary safety monitor in our BMS for a LiFePO4 stack.

    In working on the design I have run into a few apparent internal inconsistencies in the data sheet that I would like to have resolved before going into…

  • Reconfigurable battery stack AD8280 design.

    Is there a way to design a reconfigurable (i.e. via microcontroller FW and some analog switches) AD8280 design in order to implement one board for 3 to 6 cells connected in series? The number of battery stacked should be a FW hard-coded parameter.


  • RE: AD8280 - Hysteresis on OV, UV and OT Trip Points

    Hi Lorenzo,

    you ou have the correct understanding of what hysteresis should do.  Is it possible that there is a large amount of noise on the inputs to the AD8280?  Perhaps higher frequency noise that does not show up on a meter But would show up on a scope…

  • RE: BMS with Li-Battery

    Kaho,

    I am not familiar with how parallel batteries are monitored, balanced and protected.

    Analog Devices has some devices for series connected LI batteries such as the AD7280A and AD8280.

    ADI offers the main components required for a complete Li-ion…

  • RE: Lithium Iron Phosphate batteries

    Allan,

    I am not familiar with these type of batteries but in general Lithium batteries need to be charged with a constant current until they reach full charge, and then you scale back the current (CC + CV loop)

    This is typically implemented in integrated…

  • EVAL-CN0235-SDPZ评估板驱动问题

    你好,我买了一块EVAL-CN0235-SDPZ评估板,你们用的是DSP作为主控,

    (1)我现在想换STM32系列的作为主控板,不知道能否驱动EVAL-CN0235-SDPZ评估板?你们评估板上都引出了8个输入引脚(包括AD7280A的SPI通信的4个引脚,CNST以及PD,以及AD8280A的ENABLE,TEST引脚),理论上可不可行?你们公司没有对EVAL-CN0235-SDPZ评估板中的芯片写什么保护或是什么的吧?

    (2)现在我只有上次你们给我的是驱动AD7280A的程序,但该评估板上还有AD8280…
