SMD code ADSH & F1FD sot23-5 identify?

[dicky96]

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
Rich

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
