• RE: LTC4364 Failure after Reverse Input Voltage Test

    Hi Jeremy,  The absolute maximum rating is for DC survival (also refer Note 1 towards the bottom of page 4 in LTC4364 datasheet). Damage could be due to brief transients exceeding -40V. Hence, the VCC and SOURCE pins (SOURCE is pulled to input through hot…

  • Questions about ltc4364


    I am working on the output stage of my circuit which has the following context:

    • Voltage at the input of the stage is Vin = 5V (regulated)
    • At the output of the stage I have a connector where Vout = 5V, Iout(max) = 3A. The connector is meant to…
  • LTC4364 ESD Levels


    What are the ESD levels for the LTC4364. I couldn't find these values in the datasheet.

    Thanks in advance!

  • LTC4364


    I want to add a resistor (e.g. 1k) between Current_Shunt  and Sens-Pin, and a Resistor (e.g. 220K) from Vin to Sens-Pin.

    A higher Input/output Voltage difference should then result in a lower current limitation. My goal is , to better adopt to the…

  • LTC4364 VCC去耦电容

    LTC4364规格书里的典型应用,低压输入VCC都是直接接VIN;36~72输入是通过电阻接VIN, 但是图上没有显示有接VCC的去耦电容,请问这种情况下VCC是否不需要去耦电容?谢谢 Figure 10. 48V Hot Swap with Overvoltage Output Regulation at 72V, Circuit Breaker, and Reverse Current Protection

  • LTC4364 design question

    Hi Sir,

    I need an design soluction as LTC4364 but input voltage will be 15~150V DC.
    I find below description in LTC4364 datasheet
    "In the event of an input short or a power supply failure, reverse current temporarily flows through the MOSFET M2 that is…
  • LTC4364 UVLO Bouncing


    I am connecting my device to a 12V battery with the following LTC4364 load dump circuit in between.

    The continuous operating current of my device is about 2A.

    I found that the device would turn off when the battery voltage dropped to about 8.5V…

  • LTC4364: output delay


    i was trying to simulate the LTC4364 bihevior with the ciruit provided in the datasheet, but i couldn't understand why there is a delay befor the current load starts to rise ?

    could you please explain me why this happen?

    best regards,

  • LTC4364 - Design question


    we are working with the LTC4364 surge stopper, and we have the schematic below.

    We aim to protect our load from 15A maximum current, and we have not so many requirements, so we have only configured the Rsense in order to accomplish that.

    The problem…

  • LTC4364 Thermal Pad left unconnected


    In one of our designs, we have forgotten to connect the Thermal Pad of an LTC4364 to the GND plane, i.e. as the pad isn't connected to anything, there isn't any heat dissipation path for the LTC4364...

    Questions, as this aspect isn't documented…
