EDIT: Before assuming the BD92001 chip is dead, first try removing and then re-seating the ribbon cable from the touchpad module and if it still overheats or doesn't charge then it would more likely be the chip defected. [br]

Sounds like you cooked the BD92001 chip on the controller motherboard. That chip seems to break when you charge on a fast charger (always charge on your ps4 with official cables to avoid this).
Replacing the BD92001 chip requires a hot-air/infrared rework station as the chip has a big ground pad underneath it which a common soldering iron just can't reach (maybe you can get it off the board but putting a new one on will be difficult unless you use a reflow oven or a rework station). A skilled and well-equipped electronics technician would be able to replace that chip within 15 minutes assuming they had the part in stock.[br]

Here's a vendor I recently ordered the BD92001 chip from to do my own repair. [br]
Note: I have a hot-air rework station and experience with SMD rework. If you don't have those then please seek a skilled technician that can do the repair for you.
