• AD8450 and AD1972

    HI all,

    I want to design BMS by using AD8450 and AD1972, 64 pcs of batteries connect to same input source, and battery charge independently,

    AD1972 have energy recycle feature, so the energy on battery can discharge back to input bus. can 64 pcs battery…

  • RE: LDO Charger

    Hello,

    Thank you for your question. The AD8450 is a controller for a charger but doesn't charge batteries directly, rather it is the precision analog front end designed for battery manufacturing systems that form batteries. The switching functions…

  • AD8540 Current sense PGIA input offset voltage specification for Chentech

    Dear Sir

    In the AD8450 datasheet, there is a description of the current sense PGIA input offset voltage specification is +/-100uV.

    But the datasheet does not provide current sense PGIA input offset voltage specification for gain = 22,66,133.

    Can you…

  • RE: LDO 充電器

    关于LDO的问题,您完全没有回答我。而且我自己可看懂技术手册解决,不需要你再给我发链接。关于AD8450-EVALZ,我还有一些问题想了解:

    1. 预设CV的电压值,最高可以到多少?
    2. 开关式充电器的工作频率及锯齿的波纹大小?工作频率是否可调?
    3. ADC的采样频率最高可以设置到多少?
    4. 我是否可以通过外接fpga或者在电脑上做一些编程?

     

    有可能该款测试板不适合我,但是我一定会用到AD8450这颗芯片做电压和电流的测量。

    请介绍一款线性充电器,要求如下:

    1. 1. 可以编程充电终止电压至5V左右…
  • 稳定性、精度、效率……锂电池测试设备设计这些一个都不能少

    众所周知,能源消耗是全球面临的普遍问题,许多行业努力通过实现更安全、更清洁、更高效、低成本的电源解决方案来应对这一问题。混合动力和电动汽车、太阳能、风能的日渐盛行就是这种趋势的结果,而所有这些解决方案都有一个共同之处:锂离子电池。

    在电池生产环节中,其中一个非常重要的环节就是便评定电池容量和性能,为了达到这个目的就需要高功率、高效率和高精度的测试设备。为此,ADI特别推出了ADP1972和AD8450芯片方案,专为电池分容化成设备制定的芯片。ADI这款适合PWM的解决方案是目前业界唯一一款高集成度方案…
