Help with IC identification it's lettering is CW0Q
My microscope is not getting power and upon opening I have found an Ic that's burnt it's lettering is CW0Q and it has 6 pins looks to be sot23-6 package.
I picked up this used Bose Acoustimass 10 IV speaker system. Speakers seem to work fine, but the subwoofer does not make any noise. So I took apart the unit and found some obviously failed (burnt) components:
- 1x 3.14 A @ 250V main circuit fuse
- 1x bridge rectifier GBU601. there's actually two of these on the board, one is obviously burnt and the other does not seem to have any anomalies like shorts. However I figure may as well replace both.
- 2x diode. This is tricky because the only markings I see on it are: "617 402". No current rating or anything else....
I have an SSD from a 2012 to early 2013 Macbook pro, the SanDisk model SD5SL2-512G-120SE
Attached is a photo of the burnt chip. I'm assuming it's some sort of voltage regulation chip. The numbers are obscured by the damage.
I am attempting to recover data from this SSD, obviously this chip needs to be replaced before anything can be done.
Is there anything else I should check to verify the health of the NAND?
Thanks if anybody knows what part I'm looking for....
