• LTC4215 issue

     

    LTC4215IUFD # PBF is used for hot-swap management, external power supply is 12V (VCC12V) , after N-mos (IRF7413) for the back-end Buck circuit to generate 4V power for the system. The production of 100 pieces, there have been 10 pieces of suspected…

  • LTC4215 & QuikEval

    Hi,

    I want to connect my LTC4215 circuit to Quikeval software to do some debug.

    If I do this via the DC590, Quikeval needs to determine what eval board is connected, and of course there isn't one.

    Is there a way to run Qukeval where I can get to the L…

  • LTC4215 I2C (minimum SCL frequency)

    Hello!


    The table in datasheet says that minimum SCL frequency is 400kHz (see table on page 5).
    I care if that true because planned to use LTC4215 on the same bus with other device which can support I2C standard mode only (100kHZ maximum).

    Regards,
    Vic…

  • LTC4215芯片损坏问题

    目前在做项目使用了LTC4215IUFD#PBF用作热插拔管理,外部供电为12v (VCC12V_VPX),经过N-mos(IRF7413)后为后端buck电路供电生成4v电为系统使用。

    此次生产了100片,已出现了10片疑似LTC4215芯片损坏的现象,具体为在插入机箱后12v供电没能通过N-mos正常供给后端,但经测试没有过压,欠压,过流的情况,反复插拔都不行,只有更换LTC4215芯片才能修复,请帮忙分析下是什么可能导致了LTC4215芯片损坏。

    不良时具体量测值如下:

    1. pin1 (UV…
