SM5714 Power IC

The SM5714 sits right at the center of the charging and power management circuit on several Samsung Galaxy boards. When a customer walks in with a phone stuck on charging animation, one that heats up on the charger, or one that shows 0% and never moves, your first suspect on these boards should be this IC. It works as the power supervisor between the charging port and the battery management path, so a fault here shows up as charging problems even when the charging port itself tests fine.You'll run into this IC most often on A12, A13, A14, and A22 series boards, along with A8S and A52s 5G. Since these are high-volume models in the Pakistani market, keeping this IC stocked on your bench saves you a diagnostic cycle you'd otherwise waste chasing a bad charging port or a battery connector that isn't actually faulty.Reballing this chip needs the same discipline as any WLP package: clean pads, correct paste amount, and a stencil that matches the 81-ball layout. Rush the reflow and you'll get a phone that charges intermittently instead of one that's actually fixed — a callback you don't want. Pair it with a hot air station set to the right temperature profile for WLP packages and a microscope to confirm ball alignment before you seat the chip.On the software side, this IC doesn't get touched by a flash tool directly, but a hardware fault here can mimic a software issue. A board that goes dead after flash, or one where the device boots but the battery percentage doesn't move, points to this IC once you've ruled out the software path with your box or programmer. Confirm the fault with a multimeter on the charging line before you commit to removing the chip — a short elsewhere on the board can throw the same symptoms and waste your time on an unnecessary reball.Common failure patterns on the bench include boards that get liquid damage near the charging port, phones that were used with cheap aftermarket chargers for months, and units where a previous repair attempt damaged the pads during a rushed part swap. In all three cases, the fix is the same: pull the old IC, clean the pads properly, and reball with a fresh SM5714.Keep this stocked alongside your other Samsung power ICs and charging port parts — when a board comes in with charging issue and pattern unlock isn't the problem, you want the part ready instead of waiting on a supplier. For shops running high A-series volume, this is one of the ICs worth keeping in multiples rather than ordering per job.Handle it like any BGA/WLP part: anti-static precautions on your bench, a proper preheat before hot air work, and no direct flame near the board. Store spares in anti-static packaging until you're ready to use them, since ESD damage on an untested chip will cost you a callback down the line.This IC ships as a bare component for board-level reball work — it's not a plug-and-play module, so it's meant for technicians comfortable with BGA rework, not for end users attempting a DIY fix.
