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…
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…
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
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…
Hello,
I'm using the AD8280 in a Lithium Polymer Battery Pack Monitoring System as safety device (together with the AD7280A device used as main monitoring device).
While testing the system functionality I found that the trip points of Overvoltage…
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.
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…
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…
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…
通常，小型/中型混合动力汽车所需的电池电压在60 V至200 V之间。镍氢电池在这些电压和能量级别上有一定的优势。然而，完全混合/插电式混合动力或纯电动汽车通常需要300 V以上的电池组，锂电池正是理想之选。 据业界市场咨询公司的公开数据显示，目前锂电池电动车的市场份额在2.5％左右，预计三年之内将达到20％。
48V及以下电压的锂电池单元在微混动汽车和工业储能中的应用率很高。系统由13至15个锂电池单体构成。由于锂电池固有特性，需要对该数量的电池单体进行精确监测，以保障系统安全性并提高电池效率和寿命…
