Had this in beginners area but got not bites so perhaps it was the wrong forum?
This is for a 1S LiPo I am using for a project in the shed.
First let me apologize for my schematic, I've never really drawn one and I know looking at it will trigger a good many of you. The component is a SOT-26 and the marking was y1ig (Removed from PCB in pic and is marked U1 on the solder mask). I didn't draw in all of those 6 other chips (Also not able to find data on those based on markings) as they are all wired in parallel so I only drew in one. U1 is the component in question and I think it's a MOSFET and i feel it may be this one . Of course the # on the PCB comes back to nothing either. I "assume" that pin one is on the side o U1 w/ the line and if so pin 5 (Drain2) of this chip is not in use.
Thanks much guys
