Fairphone 2: Photos of the components around the charge input

I read “2603 52k c8df” currently no clue. Power Manager? According to this list there are the following chip suppliers:

Taiwan Semiconductor (TSMC) 	 Integrated Circuits
FocalTech 	                 Integrated Circuits
Texas Instruments 	         Integrated Circuits
Synaptics 	                 Integrated Circuits
Skyworks 	                 Integrated Circuits
Samsung 	                 Integrated Circuits
RICOH 	                         Integrated Circuits
Qorvo 	                         Integrated Circuits
Qualcomm 	                 Integrated Circuits
Infineon 	                 Integrated Circuits
Fairchild 	                 Integrated Circuits

Maybe the list is incomplete or it’s not even an IC.
