• LTC4412


    Does the LTC4412 part protect against reverse voltage in connecting the wall adapter and battery.


  • ltc4412

    I have a load working on SMPS with 24V,30A.i want to switch the load on 24v Battery after smps power cut.Can i use LTC4412 for this application? is micro controller require to control switching from smps to battery?  

  • LTC4412 switching to different input

    I am prototyping the LTC4412 and I have a question on how to improve my design.

    My circuit is like Figure 2 of the datasheet.


    (Sense pin is connected to Out).

    The design works and switches to higher input but only if the difference in input voltages…

  • RE: LTC4412 Voltage Drop after diode

    Sir, thank you so much. I reversed all diodes as they should be and that seems to solve the problem. I am still confused why my PCB program arranged the diodes the wrong way. I definitely learned something from this problem.

    Thank you 

  • LTC4412 Power switching Issue

    We are using LTC4412 for power supply switching between 12V SMPS power Supply (PWR_IN)  and 7.4V Li-ion Battery Power Supply (BAT_V).The Block diagram and the schematic of the power supply and switching unit has been attached.
    When I connect the AC power…

  • Use LTC4412 in My DC UPS

    My DC UPS prototype


    I need help building a DC UPS. Did I understand correctly the idea of using LTC 4412 to control fully isolated MOSFET switchs? I am suggesting to use an external switching power supply (Wall Adapter) and a backup 12V gel or LiFePo4 battery. For periodic…

  • LTC4412 - Query on dual DC power switch

    Hai Team,

    First of all thank you reading my query. We require a power path controller for switching between two 24V DC sources. One 24V DC will come from external 24V wall adapter and another will come from inbuilt 120VAC to 24V DC converter.

    Our requirement…

  • LTC4412- Power supply Switching delay

    Hello ,

       We are planning to implement a power path controller using the below circuit. 

      We need to know the tome delay between the assertion of ctrl pin and the gate and stat pin outputs when the powwr supply is switched from primary to auxillary.
