Need help to identify the 8 pins chip

I have this 8 pins chip, I guess it is a over voltage protector (input and out put are 3.3 V).
Would anyone please help me to identify the chip !!!

Thank you

Hello Banladongsong and welcome to the forum.

I was unable to ID this in my review of the photo.

Hello banladongsong,

Welcome to the DigiKey forum.

This is a challenging chip to identify.

Regretfully, Iā€™m unable to find a substitution. However, Iā€™m going to tell you what I found and hope that others in this community can assist.

I have a suspicion that this may be a power load switch possibly manufactured by onsemi. DigiKey has several offerings including:

Assuming you have a working device, perhaps you could use the datasheet information to verify the I/O and operation.

Sorry, this is the best I can do at this point. I do hope others in this community may use this information as a clue to find you a full solution.

Best Wishes,



Hello @banladongsong,

Do you have any additional information about this chip that we may use to help identify a replacement. For example, it may be helpful to identify the manufacturer and model number of the device you are repairing.



I have seen your chip. According to my information, it may be BQ2961 or LTC1696. Moreover, it may be THVD1419 (Texas instrument). All these are 8 pin chips and have the same voltage values and shape.
