• AD7280A一些问题

    我想用AD7280A来用作BMS的从控芯片,有几个小问题想要咨询。

    1.我们这款芯片有没有支持一些安全性标准,例如ISO26262这类的。

    2.我们应该选用何种MCU或者其他处理器能够与AD7280A配合使用作为BMS主从控制芯片,由于AD7280A的SPI通信等问题。有无好的推荐。

    3.我们有没有已经在电动汽车行业领域实际应用了的BMS解决方案,可否提供。

  • AD7280A: Alert signal reaction time

    Hi,

    I'm currently using the AD7280A. Everything work fine, I just can't find a specification within the datasheet.

    What is the delay time between an Alert condition detection once the conversion and comparaison is performed and the ALERT pin…

  • AD7280A:  ADC input range

    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

  • AD7280A Cell balancing technique

    Hi,

    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…

  • AD7280A real cell capability?

    Hi all,

    So I am investigating the AD7280 chip for a 400V (96 cells) Battery Management system. The question that I have is concerning the amount of cells a stacked system will be able to monitor. According to what I see in the AD7280A datasheet the number…

  • Power supply of AD7280A

    I'm using the AD7280 Li-Ion monitor IC. 4 cells(normal 3.6V a cell, max 4.2V min 2.75V) are connected to AD7280A, and voltages are measured.(vin3 vin4 vin5 connected together)

    I would like to power the IC with external power supply, rather than from…

  • AD7280A SPI通信

    您好,我在使用AD7280A芯片的时候有以下三个问题请您解答:

    1.手册里AD芯片的逻辑输入限流是10微安 而DSP的输出电流可以达到几毫安 请问在需要加限流电阻吗?

    2.请问通信时SPI接口的电压一直工作在最大额定值时会烧毁芯片吗

    3.手册里面的时序图中SCLK在空闲时是低电平,而DSP的SCLK时钟在空闲时是高电平,请问这对数据传输有影响吗

    麻烦各位老师!

  • AD7280A  data conversion initiation over Serial.

    The AD7280A  datasheet states that CNVST can be tied to Vref and data conversion initiated over Serial, but gives no further details. How is this implemented? Any code samples in any language would be helpful

  • AD7280a Cell/AUX ADC value incorrect

    We are developing a prototype of Li-ion[12Cell] Balancer using AD7280a for one of our customer.

    Initially we used fixed resistors to generate cell voltage, so voltage on each cell wrt to lower cell is 1.80V

    When reading cell/aux adc register, we see…
