    SMD code ADSH & F1FD sot23-5 identify?

    Hi guys
    These devices are in some MAG250 IPTV boxes near the power input

    I have several faulty ones but they are not all identical

    On several I have an SOT23-5 device marked ADSH. Working anti-clockwise from the dot, Pin 2 is ground and pin 6 is 3.3V supply input. Pin 5 is missing of course

    On one other I have an SOT23-5 device marked F1HD in the same location but the PCB track layout is different (there are also some extra resistors/capacitors in this area). This one has Pin 1 & 2 ground (I can see they are connected to the same track on the PCB) and 3.3V supply on pin 6. As both chips are basically in the same location I think they are performing an equivalent task - the connections to pins 3 and 4 look the same or very similar.

    Any ideas that these devices are?
    ADSH SOT23-5
    F1FD SOT 23-5

    Cheers

    The ADSH is a MAX9586AZK+T I believe. https://pdf1.alldatasheet.com/datash...9586AZK+T.html

      That makes sense, The other probably is an equivalent type thing

      Thanks

          Intermittent Power Issue with HP DV6 Motherboard Occasional Failure to Turn On
          by fixme2024
          Hello everyone, I have an HP DV6 DAOLX6MB6F2 REV: F motherboard. The issue I'm facing is that sometimes the motherboard doesn't turn on. I've checked the voltages for the power on button panel, and they seem to be okay. Right now, it's working perfectly fine, so I can't pinpoint the exact problem. I have the HP DV6-DV7 Quanta LX6_7 (Liverpool) DAOLX6MB6F2 Rev 1A.pdf schematics, a multimeter, and a 5A power supply. If anyone could guide me on where to start checking first, I would greatly appreciate it. This is my first experience with this. Thank you.

          Here, I have attached a document...

          DVR HIKVISION DS-7208HWI-E1/A BOARD DS-80104 REV 2.2 help identify burnt components
          by thesame
          Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
          The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .

          Lenovo Legion 7 - Help Identify IC
          by silver60618
          Hi gang, its a long shot, but working on Lenovo Legion Pro 7 motherboard NM-F091, and trying to identify this component near GPU with marking "eHFQH" that is burned and shorting the board. Looks like power management IC

          I couldnt find any schematic or boardview. The CPU side also has same chip. Any way to identify this chip? or take measurements from the good chip to determine what it is?

          Any help would be appreciated...

          How can I identify varistor which have been blew up?
          by chth96
          I mistakely pluged 100v japanese retro game console to 220v outlet.
          So It seems that glass fuse and varistor have been blew up.
          I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
          Is there any way to identify varistor type in my sega saturn PSU?
          Any reply would be appreciated.


          EDIT:
          It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage...

          820-000928-A Help Identify Location of this Capacitor
          by sikocan
          Hi there,
          I'm working on a A1707 Motherboard 820-000928-A and only boardview I can find it attached.

          Both legs of this capacitor are shorted to ground, well 1 leg is, the other is obviously ground. I've injected 1V maximum and 1.3amps I can not find anything getting hot and I don't want to go further. From injection I can tell top is Ground, 0V and max amp taken, bottom leg is going somewhere as 1amp at 0.05v for example.

          Could someone please let me know where this cap is going? The capacitor itself is good, test outside board is fine.

          When...
