I'm using an MCP73213 to charge a two-cell 7.4v LiPo battery using this circuit, when I tried charging the battery it was fine when I did this steps:
Connect 12V power source
Connect LiPo Battery
But when I had the LiPo 1000 mAh Battery connected and then I plugged the 12V Power Source which is a wall adapter the MCP73213 started burning and it's no good right now, I'd like some help unraveling this mistery since I don't know why this happened.
I noticed the MCP73213 is heating a lot but this IC shouldn't be burned since it has thermal regulation which reduces the charging speed whenever the temperature goes beyond 85°C (Datasheet section 5.9)
