Hello,
The AD7280A datasheet Pin Configuration section details the SDO and Alert pins and how they should be connected.
"On the master AD7280A device, the SDO output should be connected to the DSP/microprocessor. The SDO outputs of the remaining AD7280As…
There are two AD7280A chips for daisy-chain connection. After using the official initialization routine, the SPI reads back the address of the AD7280A, and sometimes the address of the second AD7280A can be read, sometimes not read.In terms of hardware…
AD7280A菊花链中的AD7280A只能放在同一块PCB板上吗？
菊花链最多能连8个AD7280A是吗？
这8个AD7280A都必须放在同一块PCB板上吗？
Hi,
yesterday i measured all cell voltages and then all filtered voltages which go directly to the voltage inputs of the chip. For better understanding i draw this voltages into the filter/protection schematic:
You can see, that most cell voltages…
hi,
i want to use the AD7280A to monitor my 36 cells hybrid capacitor which mean 6 x AD7280A.
My cells voltage range are from 0.8V to 1.6V so i want to know if this controller is suitable for my application
We are planning to use the AD7280A in Lithium Ion Battery Management system.
Before evaluation I have below queries
1- What is the principle of cell-balancing in AD7280A
2- Is cell balancing possible without controller.
Please help to suggest…
Hi Jonathan,
I am aware of these drivers and have my own that have been stable for the past two years. We have a few boards that use the AD7280A's with a logic translator 3.3V MCU -> 5V AD7280A SPI communications. These boards work fine with the logic…
Hi Erika,
The CN0235 Evaluation Board will allow you to monitor 12 batteries at once. 6 per AD7280A/AD8280 pair.
I do not believe the board is setup so that multiple CN0235 evaluation boards can be daisy chained together.
I believe you'll be able to…
