#186331 - one of these
Responding to: Chico Magalh„es's previous message
Friend, what kind of chip is this?

one of these, add selection parameters till you limit to those that fit your app, then order from digikey or see which of those you found a local supplier has.

if you click on a specific part there will be a link to the manufacturers datasheet
