Every Snapdragon 675-based board depends on a working PMIC to wake up. The PM6150-002 handles that job on the Redmi Note 7 Pro and Samsung Galaxy A70 (SM-A705F) boards — regulating voltage rails for the processor, memory, and charging circuit. When this IC develops a short or a dry joint, you'll see the classic symptoms: dead phone with no display, hang on logo, charging issue where the phone shows no response to the charger, or a board that draws current but never boots.Technicians reach for this IC after ruling out the battery connector and charging port. Put the board on a current-limited power supply first. A short circuit or abnormal current draw usually points straight back to the PM6150-002 rather than the charging IC or the CPU itself. Reflow doesn't fix this — a dead or shorted PMIC needs a full IC change with hot air or an infrared rework station, followed by proper reballing.Jumper wires won't rescue a genuinely faulty PMIC either. Some technicians try jumper lagana as a shortcut on adjacent charging faults, but a shorted power IC needs replacement, not a bypass. Fit the new PM6150-002, reflow it at the correct temperature profile, and test the board for correct voltage output on each rail before reassembly.Board-level work on this chip demands a stable microscope setup and a hot air station capable of holding tight temperature control. The IC sits under a BGA package, so misaligned reballing or overheating the surrounding components ruins the board rather than fixing it. Clean the pads thoroughly, use fresh flux, and align the ball grid under magnification before reflow — rushing this step is the most common reason a "successful" IC change still leaves the phone dead.This chip also comes up in intermittent charging complaints where the phone charges only at certain angles of the cable, or where the battery percentage jumps erratically. That pattern often traces to a partially failed voltage rail on the PMIC rather than a battery or connector problem, especially once you've swapped the charging port and ruled out software marna as a fix.For shop owners running multiple Redmi Note 7 Pro and Galaxy A70 jobs monthly, keeping the PM6150-002 in stock cuts turnaround time significantly. Diagnosing this fault without a spare part on hand means customers wait while you source the chip, and dead-phone jobs are exactly the repairs customers want back the same day.Pair this IC replacement with a proper board cleaning pass — ultrasonic cleaning after any liquid damage removes corrosion that would otherwise cause a repeat failure on the new chip within weeks. If the board shows signs of prior liquid exposure, check surrounding components for corrosion before committing to the reflow, since a fresh PMIC on a corroded board rarely holds a lasting fix.KB GSM Store ships original, tested PM6150-002 units to repair shops and service centers across Pakistan, so your bench stays stocked for the power and charging jobs that come in every week.
