RM9XG sot23-5 component

felipeab79

Hello, greetings from Auckland NZ.

I am looking for part number of this component installed on pcb board. 

I would appreciate if you can guide me to find this component.

Thanks in advance, 

Felipe

    Wild guessing here:

    You don't show enough in the picture - context is all in this kind of search.

    But I'll guess its made by ROHM (just a hunch from the R)

    If so their codes on SOT23-5 (which they call SSOP5) start with three characters of lot number and then 2 of actual part code.

    So we look up XG on https://smd.yooneed.one/code5847.html

    and find:

    But if it's not a ROHM part then this will be wrong - which is why you need to have some idea of what the part does.

    smd.youneed doesn't list any RM9 parts but does list a whole load of RM parts.

    You need to check the data sheets for them to make sure that you read the marking correctly, then think if the part might be what you've found and then check the connections and values other parts close by.

    How do you know the part is faulty ?

    HI, thanks , I appreciate your comments. I checked pcb board and found that connections for 

    this component.

     between 1 and 3 there is a bridge that is connected to the power supply (9 volts) and terminal 2 is connected to gnd. I found a short circuit to the power supply, so I checked several components and as soon as I removed this element, power supply and pcb board started.

    Tomorrow I will have a better look to the pcb to get an idea where are terminal 5 and 4 are connected.
