• ADM1270. Is there are any restrictions to use this controller in N 1 power redundancy?

    ADM1270. Is there are any restrictions to use this controller in N+1 power redundancy?

    In datasheet I found no details about pull-up pull-down mechanics in gate control of Q1 & Q2.

    Only found such parts:

  • ADM1270 Issue

    hi sir

    I  want to design the ADM1270 in my system, but I have two issue need to clarity before layout

    Q1.ADM1270 use the PMOS to be the switch, but PMOS cost Which expensive than NMOS, Why ADI use PMOS?

    Q2.ADM1270 Have reverse protect by RPFG,But I…

  • ADM1270 Reverse Supply Protection

    Dear All:

    The Hot-Swap have one important parameter "reverse supply protection". I want to know ADM1270 Input reverse supply protection maxim is how much?. the ADM1270 PrE datasheet page1 key Features show "Gate drive for low voltage drop reverse supply…

  • For ADM1270, gate output voltage is mentioned as 14-20v, but the input voltage is from 4-30v. My input is 5v, @ output side for source Vs=5v, but if Vg=14v, how my p channel mosfet will switch ON?/

  • Vsense- pin connection

    Hi,

     As per datasheet of ADM1270 hotswap controller, the VSense-  pin should be connected to drain of the FET.

    But in the eval schematics of the ADM1270, this pin is conencted to the source of a p-channel FET.

    Also, the foldback pin no 11, in datasheet…

  • RE: Hot Swap controller- UV OV OC Latch

    Hi Davorkot,

        How many FETs are you using in parallel? The heat in your circuit is most likely coming from the FET, not from the ADM1270 controller. Remember that heat is proportional to power dissipated in the FET, which is (Rdson * I^2). You can use…

  • RE: fold back assistance ADM1270ACPZ-R7

    Hi Clancy,

        As VOUT rises Vds falls, and you want to select a point on the SOA diagram where you are satisfied that the FET can take the full Vds for the time allowd by the TIMER capacitor. During fully enhanced operation the current is limited to ISET…

  • ADM1278 Monitor 12V/200A?

    Can I use the ADM1278 monitor 12V / 200A?
    What should I pay attention to when designing? (EX: Parallel MOS/Rsense)

    Is there an Excel tool like ADM1270?

  • RE: ADM1272 Iset Vsense range 2.5mV to 30mV

    Hi Marcus,

       Thanks for your prompt reply, I would like know about the availability of any other part with this range of sense voltage and which should have atleast 30V as maximum supply voltage,we found ADM1270 for our application,but the lower vense…

  • RE: current limiting device / E-fuse

    Hi Luca,

    ADI has current limiting device like the ADM1270 but I'm not really sure if this even fits your requirement. It is best that you contact local ADI support team who can take a close look at your need. Thanks!
