• LTC4357

    Hi,
    we work on a robotics system with two 48v Battery. I want to design a board in order to switch between two batteries with a load sharing system. we need a circuit with a max 40A pike. I found LTC4357 for this work. but, can I use a high current Mosfet…

  • RE: Reverse output polarity protection of charger LT3790+LTC4357

    This is more of a LT3790 charger concern and I don't think it can survive. I recommend you contact a local ADI field engineer for further support.

    For example, if we assume charger output is current limited, the input of LTC4357 is pulled to -23.3V…

  • LTC4357

    I would like to use the LTC4357 controller with input voltage range from 60V down to 0V while powering Vdd pin from external (12V for example) bias supply.

    Is there any reverse leakage current increase in the configuration described above?

    Would the MOSFET…

  • RE: LTC4357 Ideal Diode Circuit

    Hi Zuchang,

    You do not require the Schottky diode. LTC4357 controls the FETs such that highest voltage supply  will cater to the load. 

    In the above situation , LTC4357 will drive the FET M1 off and only PSB will supply the load.  There will be no reverse…

  • Maximum voltage rating of LTC4357

    Hi ADI experts

    I have a application that needs ideal diode but  the Vin source may be up to 84V

    though the recommendation operating voltage of LTC4357 is 9-80V, but the max rating of Vin and Vout pin is 100V

    May I know if this part is ok for my application…

  • LTC4357 100V Application

    Hello, 

    Is it possible to use LTC4357 for 80V+ voltage oring by ground shifting as shown below?

  • LTC4357 Model - Potential Issue

    Hello,

    I'm attempting to design an ideal diode capable of operating with an input from 16V to 40V, and driving up to 25A of current. The design utilizes Infineon's IAUT300N08S5N012, which should be overkill for the voltage and current requirements…

  • Ideal Diode Controller

    I am using LTC4357 FET controller as ideal diole

    The MOSFET I have chosen (Infieneon IPT007N06N) has Rds of 1m Ohm.

    At DC isn't the Pd just I^2 +Rds?

    If so, it doesn't match the DC limit on the SOA curve, which doesn't graph past 0.1Vds.

  • RE: Automatic Switchover from a Battery to a Wall Adapter with a Battery Charger

    Hi Gao,  For above 18V, we only have ideal diode controllers such as LTC4357 (single), LTC4359 (single), or LTC4355 (dual) but no current balancing IC. With ideal diode controllers, there will be some droop sharing based on board trace and MOSFET resistances…
