PM886EAD POWER IC

The PM886EAD sits in the power management layer of the motherboard, acting as the supervisor IC that controls how voltage reaches the rest of the board. On the Samsung G531 Grand Prime VE, G361F Core Prime VE, G388F Xcover 3, and J100 Galaxy J1, this chip decides whether the phone powers on at all. If the supervisor rail doesn't come up clean, you get a dead phone that won't respond to a charger, won't show a charging LED, and won't boot past the logo — even though the battery, charging port, and display are all fine.This is why the PM886EAD comes up so often in dead-board diagnostics. A technician running current on a DC power supply will usually see either zero draw or an abnormal short when this IC has failed, which narrows the fault down fast compared to chasing individual voltage rails one by one. Boot loop issues, hang on logo faults, and phones that go dead after flash often trace back to a damaged or poorly reflowed power supervisor IC rather than a software fault — so before you spend time on a repeated software marna attempt, it's worth confirming the power rail is stable first.Since this is a BGA package, replacement is a reballing job, not a simple solder-and-go swap. You'll need a hot air rework station set to the correct profile, flux, BGA reballing stencil or paste, and a microscope or magnifier for placement accuracy. Getting the reflow temperature and dwell time right matters here — overheating the pads risks lifting traces on these smaller Samsung boards, and underheating leaves cold joints that come back as an intermittent charging issue or random restarts a few days later. Clean the pads thoroughly, check for lifted pads under the microscope before placing the new IC, and reflow with steady, even heat rather than direct blasting.Board-level technicians working ISP, eMMC, or UFS-based repair services will recognize this chip as part of the wider Qualcomm PM-series power IC family used across Samsung's Snapdragon-based J and G series lineup. Keeping a few PM886EAD units on the bench means you're not waiting on a supplier every time a dead G531 or J100 comes in — a common repair request in Pakistani service centers given how widely these models still circulate.KBGSMSTORE ships this as an original, tested unit — not a generic aftermarket clone — so what you install matches the factory power specification the board was designed around. For shops handling volume repair work on entry-level Samsung devices, this is a part worth keeping in stock rather than sourcing per-job.
