Anybody knows the PN of this device? it was labelled mcp73213t-a6x/mf but the datasheet shows a different device marking. Any help is greatly appreciated.
Thank you for contacting DigiKey , The data sheet shown on our web site does not list all the parts in that series but I did find that part on the manufacturer web site , however they do not show any part markings for it . https://www.microchip.com/en-us/product/MCP73213 you may want to contact them to get part marking info for that part https://www.microchip.com/en-us/about/contact-us
Assuming the reference to the MCP73213 is from a reliable source, then I would guess that perhaps it is one of the many flavors of that part. The datasheet only gives example part marking of a few of the “standard” parts, but there are many variations, as seen here. There may also be custom versions which would further expand the possibilities. The fact that it shows a “Z3” leans toward it being one of the MCP73213 variants but, unfortunately, the documentation does not seem to show how they mark every variant.
