• LTC4417 Droop


    The load is 66-120W and this could be 3.5 to 13.89Amps. It has a voltage range of 8V98-18V11.

    I am using the LTC4417 PowerPath Controller Design Tool to design three power sources.


    The tool suggests a 26V9 droop could occur…

  • 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…
  • LTC4417 external hysteresis set.

    Hi guys,

    I am developing the backup power system for the unmanned system with LTC4417 ( In fact, my original plan was to use LTC4421)

    My system has two power sources one is the rechargeable battery with solar panel and the other one is the non-rechargeable…

  • LTC4417 Maximum Output Current


     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?

  • 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 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…

  • Design using LTC4417


    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?

  • 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…
