Help to identify 8 pin IC

[nikolayu]

Hello everyone.

I need help identifying and replacing a burnt IC.
The device is a Garmin dezl 870 with a charging problem (not charging). I opened it and I see that one IC is burnt so I can't read what it is so I can replace it.

Does anyone know what model it might be?

Tnx for info.
I just saw that on other side I have also burnt component (I think its ag1 like the one on left side), but I'm unable to find what is it. Do you know what part is that?

seems the same since we see a small bit of the numbers on the burnt one ??

[nikolayu]

It's look like the same but I don't know what component AG1 is so I can order it and replace.

give me this loll  but not an sot-323  6 pins ??

AG1

GA4A3Q
NEC Electronics
SOT-323
NPN transistor
Sw, 60V, 100mA, 200mW, R1/R2=1k/10k

i would vouch for the previous answer
  if you have an ohm meter or diode test ...

If it helps, "KD + Y" appears to be an NTK3139PT1G P-ch MOSFET.

This is 3 pin.
One from picture is 6 pin

here are the readings both diode and ohms

[fzabkar]

Pins 2 and 3 look like Ground and Vcc, respectively. If so, then that would invalidate my previous guess.

"aG" is 74AUP1G332GW, but it seems very explicit about the "A" in lowercase.

[nikolayu]

Here additional details that I found.

Its something with USB pins.

I found AG1 at USB port.

[fzabkar]

It looks like it must be an ESD protection component, perhaps a TVS diode array?

Could it be something like this?

Yeah totally seems the case.
