AXP209 power management module gets hot

Recently I have accidentally reversed power on my Banana PI. After that I’ve noticed that power management chip (AXP209) started to get really hot. Regrettably, I can not specify exact temperature now.

I never payed too much attention to it, so I don’t know whether it was always like that or it’s a result of applying reverse voltage.

The device successfully boots and works, although I’m concerned of burning it in case power management module is damaged.

So, how can I verify if something bad really happened to it?

are you use 5V/2A adapter for it. ???

Well, I’m using ATX power supply. Usually. And I’ve checked it with standard usb charger also. It acts in the same way in both occasions.
