Can anyone please identify this 6-pin SMD integrated circuit, or tell what it does? I could not find it by the code written on it.

It is from a solar charger controller and I need to replace it.

Could be MP2459. The pinout seems to match your board.

Datasheet says AEQ top marking but isn’t 100 % clear on other markings and shows an example with four characters. enter image description here
