enter image description herePhoto of unknown device on PCB

I need some help identifying this SMD part. It has F1TL marking and is on a 3-axis gimbal daughter board. There’s 3 on the board and 2 are burnt. Thanks in advance. [6-pin SMD, 3x2mm in size approx.] 2 more image’s, hope they help.I believe the gimbal ended up in the sea, the battery pack suffered, (replaced), I need to replace these so as to aid further testing. Strip down of the unit could be destructive. enter image description here Thank you for the help, I’ll do some more testing and see if the units repairable or scrap. Thanks again.

    \$\begingroup\$ Paul Rimmer - Hi, That looks like a SOT23-6 package so I added that & the main part of the top marking into the title, to help future searches. Can you also add a photo showing more of the PCB, to give some more context? Also, have you tried doing any reverse-engineering of the schematic, to help show how the unknown components are part of the overall design? If so ,please edit the question & add that image. The current photo shows the unknown device close to a connector. Are all 3 devices close to connectors? Do you know what event damaged the devices? \$\endgroup\$

  • \$\begingroup\$ Paul Rimmer - Thanks for the update. (a) The photos show all 3 devices are near the same connector, so if the accident led to excessive / wrong polarity voltage on that connector, this could explain why 2 of the 3 devices were clearly damaged (and the 3rd one might be damaged internally too). (b) Now seeing the full PCB, it's not possible to reverse-engineer the relevant parts remotely using just the photos. However where we can see the PCB tracks going to those devices, we see that the tracks to pins 1 & 3 are thinner than others. That fits with the identification in the answer. \$\endgroup\$

Most likely it is a AO6601 MOSFET, a complementary n and p channel pair in a single package.
Here is a package marking description.
And here is a datasheet.
