PM8009 001-00 Power IC

Board-level power faults are some of the toughest jobs on a repair bench, and the PM8009 001-00 sits right in the middle of that puzzle on a lot of Snapdragon-powered boards. This isn't the primary PMIC — it's a companion chip. Qualcomm's SPMI PMIC family splits power management duties across more than one IC on modern boards, and the PM8009 handles a defined set of voltage rails while the main PMIC (often a PM8150-series or PM8250-series chip depending on the platform) manages the rest. Linux kernel driver documentation for Qualcomm SPMI PMICs confirms the PM8009 as part of this companion PMIC lineup, with a dedicated PM8009-1 revision built specifically for the SM8250 platform.For a GSM technician, that division of labor matters. When a phone comes in dead after flash, dead after drop, or dead after a short from a battery fault, your first move on the bench is isolating which power domain actually failed. If your ISP box or boot log shows the main PMIC responding fine but a specific voltage rail never comes up, the fault sits with a companion IC like this one — not the main power chip. Reflowing or IC change karna at that point saves you from unnecessarily pulling and testing the main PMIC, which is a bigger, riskier job on most boards.The PM8009 001-00 ships in a BGA package, consistent with how Qualcomm packages its SPMI PMIC family for board-mount applications. That means proper hot air control matters here — too much heat risks lifting neighboring components on a densely populated power section, and too little leaves you with a cold joint that reintroduces the same fault after reassembly. A calibrated hot air station and a microscope for post-reflow inspection are your best friends on this repair.Where this chip shows up most in real repair work is Snapdragon-based smartphone boards using SPMI-based power architecture, with SM8250-based platforms specifically documented as using the PM8009-1 revision. Boards showing hang on logo after a power-related repair attempt, boards with a dead section that survives a full software marna attempt, or boards that draw current on your bench power supply but never boot are all candidates for a PM8009 check before you move on to bigger, more expensive components.Because it's a companion IC rather than the board's central PMIC, replacing the PM8009 001-00 is a more targeted fix than a full power IC swap. You're not touching the main charging or battery management circuit — you're addressing one specific rail. That keeps the repair contained, reduces the chance of a cascading fault, and gets the board back to the customer faster when your diagnosis is right.Keep genuine, verified stock of this IC on your bench rather than substituting a similar-looking part. PMIC families across Qualcomm platforms aren't interchangeable even when markings look close, and a mismatched substitution risks a second dead board instead of a fixed one.
