• LTC4417 Gate falling to slow before switchover

    Hi there

    I use the LTC4417 in following application:

    • On V1: 12V from PoE
    • On V2: 9-30V DC-Input
    • On V3: 9-30V DC-Input

    I have the following problem, when switching from V3 with 30V to V2 with 9V:

    • The gate voltage of transistor at G2 (after inrush-limiting…
  • RE: LTC4417 output discharge

    Thanks for your answer, this is really helpful!

    When using the CAS pin method, which NFET did you use? I noticed that the CAS pin has a typical output high voltage of 2V, is this above the threshold voltage of the FET and does the FET turn on fully?

  • LTC4417 Maximum Output Current

    Hi,

     I am pretty overwhelmed with the terms in the LTC4417 datasheet. I just want to ask what is the maximum allowable output current at the load side?

  • LTC4417 Shutdown Input

    We intend to use the LTC4417 to select between 2 battery packs and a converter.  However, we will have an enable switch located 15+ feet away.  We'd like to connect this switch to the Shutdown Input.   Is any debounce circuit required on this input or…

  • RE: Understanding the LTC4417

    Hi Troy,

    First my apologies for the delay in responding. 

    The EN pin has to be greater than 1V for the LTC4417. In the standard demo board configuration the EN pin is powered from Auxiliary Voltage input.

    I am assuming that you have followed these instructions…

  • LTC4417 Shuts Off

    I have an implementation with LTC4417 to switch between an AC adapter, main battery, and backup battery.

    When running, it will randomly turn off. I have checked the EN pin after it shuts off and it is at 1.8-1.9V which is above the 1V cutoff specified…

  • LTC4417 UV/OV Hysteresis

    I have the UV and OV resistors set so that UV is 9.1V and OV is 14.5V. I have the HYS pin grounded which should set the hysteresis to 30mV. The UV and OV thresholds work properly however once I hit the threshold I can go all the way through the voltage…

  • Design using LTC4417

    Hi!

    I'm designing a miso converter and I'm planning to use LTC4417 for current sharing I was wondering if it's okay to use it even if I have a 4A max current?

  • General Spice Model for LTC3621, LTC8606 & LTC4417

    Hi Team,

    In our system we have couple of power regulators LTC3621 , LTC8606 from analog devices and TPS63070 from TI.

    We are performing analysis for ripple measurement, Load/line regulation independently in LTspice for ADI parts and TINA Tool for TI part…

  • LTC4417 reverse battery protection

    Hello,

    I am designing a system with a user-replaceable battery.  Our Mech Engr can't provide reverse insertion protection.  (Of course, no amount of labeling will be sufficient.)  The battery will be a single Li-ion battery (~3 - 4.2V).  The V1, V2,…
