Power Control IC For Samsung Galaxy Fit S5670

The Power Control IC — or PMIC — in your Samsung Galaxy Fit S5670 is the central power management chip that regulates and distributes the correct voltage to every component on the motherboard — the CPU, display, RAM, cameras, sensors, and all peripherals. It also manages battery charging, power sequencing during boot, and sleep-state power reduction. When it fails, your Samsung Galaxy Fit S5670 loses regulated power across all systems — causing complete failure, random shutdowns, or boot loop.

If the battery is confirmed healthy and the charging circuit is functional — but the device still will not power on, shuts down randomly regardless of battery level, or loops through the boot screen — the Power Control IC on your Samsung Galaxy Fit S5670 motherboard is the likely cause. A board-level technician can confirm by measuring the voltage rails output from the PMIC with a multimeter.

PMIC failure is less common than peripheral component failure but is one of the most impactful board-level faults when it does occur. It is most commonly caused by liquid damage reaching the motherboard, a power surge from an incorrect charger, physical shock damaging the chip's solder joints, or general component degradation over the device's lifespan on your Samsung Galaxy Fit S5670.

No. The Power Control IC is a large, complex BGA chip soldered onto the Samsung Galaxy Fit S5670 motherboard. Replacement requires advanced BGA reballing skills, a professional rework station with precise temperature profiles, a microscope, and extensive board-level repair experience. This is one of the most technically demanding repairs in mobile servicing and should only be attempted by highly experienced professionals.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip has been soldered it is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
