PM6375 001 Power ic

Every Xiaomi 12 and Xiaomi 12 Pro motherboard runs its power distribution through the PM6375 001. Instead of one flat 5V rail feeding everything, this PMIC breaks incoming power into multiple regulated outputs, each tuned for a specific block on the board — the SoC, RF front end, display, and charging path all draw from separate rails managed by this single chip. That's the core job of a PMIC: sequence the power-up correctly and keep every downstream component fed at the right voltage.You'll usually meet this IC on the bench, not in a spec sheet. A phone comes in completely dead, or it charges but never boots, or it hangs right on the Mi logo — and after ruling out the battery, charging port, and obvious display damage, the PM6375 001 sits high on the suspect list. Run your board on a DC power supply and watch the current draw. A short circuit, an abnormal current spike, or zero draw at all on a known-good battery all point back toward the power rail this chip controls. Thermal imaging under load often confirms it — a hot spot right where this IC sits on the board tells you the story before you even lift it.Replacing it is a BGA job, full stop. You're not soldering wires here — you're pulling a ball grid array chip off the board with hot air, cleaning the pads, and reballing before mounting the new IC with a stencil matched to its footprint. Set your hot air station carefully; too much heat lifts neighboring components or warps the board, too little leaves cold joints that fail again within days. Work under a microscope for pad alignment — at this pitch, eyeballing it isn't an option. Clean flux residue thoroughly after reflow; leftover flux under a PMIC causes intermittent faults that come back to your bench weeks later with the same complaint.This chip ties directly into your CPU repair and PCB repair workflow — it's not an isolated part. If a customer reports charging issues alongside random reboots or the phone dying under load, check this IC before you jump to CPU-level faults; a failing power rail mimics processor problems more often than technicians expect. Pair your reballing work with a decent multimeter for rail continuity checks, and keep a test box or diagnostic tool on hand to confirm the board boots clean after the swap.Stock condition matters here. Source your PM6375 001 from a reliable batch — mismatched or counterfeit PMICs cause boot loops even when the reballing job itself is clean, since the internal regulation doesn't match what the board expects. Genuine parts hold consistent output across the rails; off-spec chips drift under load and bring the customer straight back to your shop.Keep this IC in your Xiaomi 12 series inventory alongside your soldering accessories, reballing stencils, and a working microscope. Board-level repair on this generation of Xiaomi devices comes up often enough that having stock on hand — instead of waiting on a supplier — keeps your turnaround time where your customers expect it.
