hi,

I have a lithium battery monitor of a laptop on my hand but can't identify de id for the datasheet. Anyone could help me please? It has a Sanyo firmware inside. The laptop is a Samsung np270e5e.

The reference on the IC is 3122104D 60020

Were you hoping to find another one? I think you can give up on that. Finding a similar laptop on the used market might get you one.

Since you can read the eeprom, it seems like it might be functioning. What are you trying to do?

 

i want to identify the IC if it's one like bq30z55 or series

I think if it was a TI part, they’d put the logo on it.

Where did you se the IT logo on the picture?

I didn't, that's my point. The BQ30Z55 you mentioned is a TI chip. They'd likely put a logo on it if it was their's. However it's only for certain OEMs, so maybe not.
