• RE: LTC4041 - SYSGD Comparator

    Hello,

    Interesting idea. We do not see an issue with this. The comparator is powered by Max(VIN, VSCAP) so power will not be an issue, and these signals are not used for any internal logic.

    Bear in mind that there is a CAPGD signal already, but it does…

  • LTC4041 behavior after CHGEN & BSTEN release

    Hi Everyone!

    I have a question regarding the CHGEN & BSTEN pins.

    In a scenario where the input voltage had failed, and the LTC4041 started to supply voltage to the circuit using the boost converter: If I pull the CHGEN & BSTEN pins high to shutdown…

  • RE: Reserve Power for Small PCB board 16Watts, 4A, LTC3350 or LTC4041?

    Hi Joe, If you need 3.3A output then the LTC3350 will be better. If you only need 2.5A or less and do not need telemetry then the LTC4041 would be a simpler solution.

  • Question about the LTC4041 PFO  pin, is possible to use a pull-up in this pin before can be connected to GPIO. I guess and to be clear my question  how to wire the Open-Drain Power-Fail Status Output with a processor does it requires a pull-up?

  • LTC4041EUFD#PBF and LTC4041IUFD#PBF difference

    Good day!

    Please tell me the difference between LTC4041EUFD#PBF and LTC4041IUFD#PBF. I found no differences in the datasheet, but the price varies.

  • LTC4041 backup模式切换问题咨询

    您好,我确认一个LTC4041切换到Bakup模式的问题。

    1.LTC4041从normal模式切换到backup模式,超级电容放电电流产生一个明显过冲,请问该电流是如何产生的?该电流是否可以估算,可否提供估算公式?

    2.芯片手册pp.20页,超级电容选型章节,对超级电容的最大放电和充电电流有要求,请问是否在任何条件下,超级电容的峰值电流必须大于7.5A? 如果系统中的负载电流比较小,是否也必须满足该条件?关于超级电容峰值电流的要求,是否有计算公式可以依据?

    3.芯片手册pp.20页,超级电容容量计算公式不太理解…

  • LT4041 Assistance

    Hi all,

    I am using the LTC4041 in a new application. For backup I am using a 3V, 5F capacitor. System voltage is 3.3V.

    It appears that my actual charge current is not what is programmed by the PROG resistor. It is currently programmed to be 1A, I believe…

  • LTC4041 超级电容充电电路异常求助

    你好:cai

          我按照官网推荐电路设计了一个LTC4041的超级电容充电电路,输入4.7-5.5Vdc,设置输出5V, 超级电容为2节3000F的超级电容串联。设置的充电电流为2A。

    但是实际测试 时:

        1.在没有介入超级电容时,输入电压5V,输出电压只有2.6V,输入5.4v时输出5V。

        2.介入2节3000F超级电容,输入5V,没有接负载的情况下,总电流为0.接入5V,1W负载的情况下,输出电压马上被拉低了,只有2.7V左右,需要将输入电压上升至5.4V才能输出4.7V。

        3.当接入负载大于2W时…
