  • RE: Replacement for ADG439FB

    Davidforde
    Davidforde

    Hi,

    Our latest overvoltage protection multiplexers are the ADG52XXF family. The ADG5209F or the ADG5249F are both differential 4:1 devices and are the highest density devices we currently have.

    These devices are available in a 4 mm x 4 mm LFCSP package…

    Hi Kiran,

    Once Vdd is removed all the switches will be off.

    Just out of interest have you had a look at the newer versions of these devices the ADG5209F or the ADG5249F?

    Regards,

    David

    Q 

    Are these parts pin-pin compatible with existing parts?

     

    A 

    Yes, the ADG5208F/ADG5209F are pin-for-pin compatible with the ADG5208/ADG5209
    and ADG1208/ADG1209. They are drop in replacements if overvoltage protection is
    required. However…

    Q 

    What happens to the output during an over-voltage event?

     

    A 

    The drain output will be clamped during an overvoltage fault condition. The
    ADG5248F, ADG5249F, and ADG5243F have secondary supplies (POSFV, NEGFV) which
    will be the clamp voltages…

    Q 

    What are the system benefits of fault diagnostics?

     

    A 

    For systems that are sensitive during a start-up sequence, the active low
    operation of the fault flags allow the system to ensure that the ADG5248F is
    powered on and that all input…
