MT6325V Power IC

When a board comes in dead and the charging circuit tests clean, the fault usually sits on the power management line — and that's exactly where the MT6325V comes in. This MediaTek PMIC handles voltage regulation and power sequencing for the mainboard, so when it fails, you typically see a phone or tablet that won't power on at all, one that dies right after a flash attempt, or a device that keeps hanging on logo because the rails feeding the CPU and memory never stabilize.Physically, the MT6325V comes in a BGA package, which means you're working with reballing tools, a hot air station, and flux — not a soldering iron alone. Supply voltage runs between 1.0V and 6V, with a power dissipation rating of 0.6W, figures that matter when you're checking the chip against a multimeter reading during diagnostics or comparing it to a donor board before you commit to IC change karna on a client's device.This chip is a common point of failure on the Lenovo A-series and Vibe lineup boards it supports. If you're seeing a dead phone after liquid exposure, a board that draws current but never boots, or a unit that was fine before a failed software flash and now shows zero response, pulling and testing the power IC belongs early in your diagnostic sequence — before you start chasing software faults that don't actually exist.Reballing this part demands a controlled process. Preheat the board evenly, keep your hot air station at a steady, moderate temperature to avoid lifting neighboring components, and always verify ball alignment under a microscope before reflow. A misaligned BGA on a power IC won't just fail to fix the issue — it can create a fresh short and turn a straightforward repair into a burnt-board situation. Clean the pads thoroughly after removal, apply fresh solder balls sized for the package, and reflow with consistent airflow across the entire footprint rather than concentrating heat in one spot.In your workshop, this IC typically shows up alongside jumper lagana work when a trace near the power rail has lifted, or as part of a full board-level diagnostic when a customer reports a hardware fault that software tools can't touch. Pair it with a bench power supply during testing — if the board pulls current but the display and charging IC still don't respond after replacement, the fault may extend beyond the power IC itself, and that's worth confirming before you close out the job.Stock condition matters here. Always source new, unused stock for board-level repair rather than pulled units of uncertain history, since a marginal power IC can pass a quick bench check and still fail within days under real load. Keep the chip in its original packaging until you're ready to reflow, and avoid handling it without proper ESD precautions — PMICs are sensitive to static discharge even when they look mechanically fine.For technicians running a busy repair bench, having verified MT6325V stock on hand cuts diagnostic-to-repair turnaround significantly on the specific device models it supports, rather than waiting on a special order once you've already confirmed the fault.
