PM4250 000 Power IC for Vivo Y20 – Original and Tested

A dead Vivo Y20 sitting on your bench with zero current draw almost always points back to the power IC before you touch anything else on the board. The PM4250 000 sits at the center of the phone's power tree, and once it degrades or shorts, the board stops responding to charger input entirely. This listing gives you a fresh, tested PM4250 000 to swap onto the mainboard and bring the device back into a working state.Supply voltage on this IC runs between 1.0V and 6V, which matches the low-voltage rails the Vivo Y20 mainboard depends on for baseband and application processor startup. Dissipation power sits at 0.6W, keeping thermal load manageable during reflow and normal operation once it's back on the board. The BGA package means you'll need a hot air station set to a controlled profile and a decent flux to seat it cleanly — rushing the reflow on this chip is one of the fastest ways to create a repeat dead-after-flash case.You'll run into this chip most often on three types of jobs. First is the classic dead phone that shows no current draw on the power supply at all — no LED, no vibration, nothing on the ammeter. Second is a board that was working, went through a bad flash or corrupted firmware update, and now sits at dead-after-flash with a shorted or leaking power rail. Third is intermittent power behavior, where the phone boots sometimes and not others, often tracing back to a weakened solder joint or a partially damaged PM4250 000 rather than a fully dead one.Before you commit to changing the IC, confirm the fault actually sits at the power stage. Check for a dead short on the battery connector pads, test current draw at the bench supply, and rule out a swollen or faulty battery first — a battery-side short will mimic a power IC fault and waste your reflow time on a chip that wasn't the problem. Once you've confirmed the short or the dead rail traces to the PM4250 000 footprint, remove the old chip with your hot air station, clean the pads thoroughly, and reball or direct-place this replacement.This isn't a universal power IC — it's built for the specific voltage architecture used on the Vivo Y20 and shares its footprint with a small group of Redmi Note 9 series and Motorola G Play boards that use the same power design. If you're working across multiple brands in your shop, keep this chip labeled separately from other PM-series ICs since a wrong-model swap on a similar-looking footprint won't power the board correctly and can damage the mainboard further.Every unit here ships tested, not just pulled and repackaged. That matters on power ICs specifically, since a bad power IC installed on a working board can take out other components downstream through voltage leakage. Keep your workshop stocked with this part if Vivo Y20 dead-board jobs come through regularly — it's one of the more common power failures on this model, and having a verified-working replacement on hand saves you a diagnostic delay mid-job.Handle the chip with anti-static precautions until you're ready to reflow it, and store any unused stock in a dry, sealed environment — moisture exposure on BGA components before reflow is a known cause of popcorning during hot air rework.
