MT6350V Power IC

When a phone comes in completely dead — no charging light, no logo, nothing on the screen — the power management section is usually the first place you check. The MT6350V handles exactly that job on MediaTek MT67xx-based boards. It distributes voltage to the CPU, memory, display driver, and charging circuit from a single chip, so when it fails, the whole board goes dark.You'll see this IC on your bench most often with dead phone complaints where the battery doesn't charge at all, or where the device hangs on logo no matter how many times you reflash it. A damaged PMIC also shows up as a phone that charges but never powers on, or one that draws current but stays completely unresponsive. Before you jump to IC change, always rule out a shorted charging port or a damaged battery connector — a lot of "dead after flash" cases turn out to be a power rail short rather than a bad chip.The MT6350V ships in a BGA package, which means you're reballing it onto the board rather than soldering discrete pins. On your repair bench, that calls for a hot air station set to the right temperature profile for BGA work, decent flux, and a steady hand under the microscope to line up the balls before reflow. Rushing the reflow stage is where most technicians lose boards — give the pads time to heat evenly and let the chip settle into place with the natural surface tension of the solder.This is sold as a compatible replacement IC, not an OEM-pulled original, so it's built to match the functional footprint of the factory chip rather than carry a manufacturer's original packaging. That makes it a practical choice for repair shops running through volume — you're not paying for donor-board sourcing, and you get a fresh part every time instead of a used or reflowed unit off a scrap board.Where this chip fits in your workflow: diagnose the dead phone first with a bench power supply to check current draw, isolate whether the fault sits on the power rail or elsewhere on the board, then move to IC change once you've confirmed the PMIC itself is the failure point. Skipping the diagnosis step and jumping straight to IC change wastes both the part and your time if the real fault lies somewhere else — a shorted component downstream can keep pulling the new chip into the same failure.Board-level technicians working on Xiaomi Redmi 3 and Meizu M3 Note repairs will recognize this chip as a common failure point on those boards, particularly after liquid damage or a bad charging cable that sent a voltage spike through the circuit. Keep a few of these in your reballing kit alongside your stencil and BGA jig if you handle MT67xx-series repairs regularly — it saves a supplier delay when a customer is waiting on a same-day fix.Store the IC in an anti-static bag until you're ready to use it, and handle it with an ESD wrist strap during reballing. Power ICs are sensitive to static discharge, and a damaged chip straight out of the packet is a frustrating way to lose a repair job before you've even started.
