Part Number: TPSI3050

Tool/software:

  

Hi sir,

     I am having doubt in the above circuit in which all the components are connected by your refference circuit . I want to drive a mosfet for Switch a 24V dc supply . and also i want an axillary circuit to send signals to my controller from vddm ,can i connect the controller GPIO directly to that VDDM or should i need to connect any thing extra in this circuit .i need your guidence.

                                                                                                               Thank You

    Hello Manoj,

    Thanks for reaching out to our team on E2E.

    VDDM is typically used for powering circuitry on the secondary-side, you can treat this as an isolated 5V supply. I am not sure what kind of signals you want to send to controller, can you please share more information about your application?

    Best regards,

    Thank you for your reply Tilden Chen,

    We want to send a feed back signal from the vddm pin ,this signal is for our internal purpose to check whether the ic is in active state or not . while reading data sheet its mentioned that the vddm pin can supply a 5v output ,so can i use that out has a digital output so that i can use that signal for my feedback signal ....my application want that feedback signal for confirmation of the 10V VDRV  supply is driving mosfet by checking the vddm pin ... this is the purpose of my application to detect the IC status . waiting for your reply ...
