Hi everyone,
Please help me to identify the chip with TOP marking “B7”. It is in a DFN-10 (3mmx3mm) package.

Hi @zhili.dou,

The bottom line should have 3 digits/letters on it. Unfortunately, it is not very clear in the picture. Can you please confirm the same? I can read it as 39

Thank you

Hi,
Thank you very much for your reply. After reviewing, the three digits on the bottom line are “397.”

Best regards,

Zhili
