• RE: LT4356-1 automotive grade in progress


    Yes, there is a plan to release an automotive grade of this part and it will be out soon.

    Please contact your local ADI sales representative for more details. Thank you. 



  • LT4356-1 & LTC4364-2 negative protect


    With a Ideal Diode function (LTC4364-2), it has a unique technique.

    If reverse current develops, a 130mA fast pull-down circuit quickly
    connects the DGATE pin to the SOURCE pin, turning off the MOSFET.

    But why this operation can Holds Up Output Voltage…

  • LT4356-1 Surge Stopper in Hazardous Environments


    how can I start to design a circuit to meet harmonized standard, IEC60079-11 ?

    Does there any concern to change components on demo board DC1018A (LT4356-1) circuits to meet Intrinsic Safety ?

    What's the key design points on it ?

    Do we have design…

  • min spec of pull-up current of LT4356-1

    The Gate pull-up current of LT4356 is specified at -4.5uA (min), -30uA(typ), -50uA(max) for Vgate = 48V, Vcc =48V. I was wondering under what conditions the gate pull-up current can drop to -4.5uA.



  • LT4356 : easy way to remove auto recovery timer on an already existing hardware..


    I'm using a LT4356-1 to control the power of motor controllers. Everything seems to work as expected. We are able to soft the start to limit the inrush current of the controller's input capacitors, and current limitation of 50A (shunt resistor of…

  • LT4356 fried by minor overvoltage


    we have an issue with a LT4356 getting fried during in-house lab testing. Its voltage clamp is set to about 39 V, and during static overvoltage conditions (tested by providing a continuous 45 V to the input), the IC malfunctions in a way that it stops…

  • LT4363 & LT4356 : Mos and Rsense


    I can't figure out what's the benefit between this. ( LT4363 & LT4356 : Mos and Rsense )

    Why LT4363 change the location, Mos in front of Rsense.

    Does there any benefit on it?

    Please kindly help with this.

    Thanks a lot !

  • LT4356-3 anomalous behavior

    Using the LT4356-3 device we find an its anomalous behavior: on an overvoltage event on the Vcc we obtain a final state of the device out of specification with a FLT signal low, but the OUT pin active (high).

    What could determine such an anomalous behavior…

  • RE: LT4356 along with SMPS filtering

    Hi, does the same apply for the common mode choke also?

    Is the sequence to be

    -Add a bidirectional TVS diode

    -Add a reverse protection diode

    -Used a surge stopper device to protect the input of the boost

    -Add a common mode choke

    -Add a damped L C filter…

  • LT4356-3 operating during short circuit


    i would like to use the LT4356-3 as short circuit protection. During a short circuit event it can happen that the input voltage drops to a very low value due to high line impedances between source and LT4356-3. The voltage drop last only for a few…
