The MAX77854 is the power management IC used in the Samsung Galaxy S7 (SM-G930F) and Galaxy S7 Edge (SM-G935F). This BGA chip handles voltage regulation, buck-boost conversion, and battery charging control for the CPU, GPU, and memory sections of the board. It is the go-to replacement part when a technician diagnoses a dead phone, no-charging fault, or a board that stays completely unresponsive after a drop or liquid exposure. Reballing and reflow work on this IC is common in Pakistani repair shops handling S7 series boards, since a damaged power IC often looks identical to a dead battery or charging port fault until proper diagnosis rules those out.
