PM7325 000 Power ic

When a Snapdragon-powered phone shows no charging response, dead after flash, or a board that won't power on at all, the PM7325-000 is one of the first ICs a technician checks. It works as an interface PMIC that supplements the board's master core PMIC, taking on battery charging, USB power delivery, and general housekeeping functions so the main PMIC isn't overloaded.On the charging side, this IC runs a high-efficiency 4A two-level buck Li-ion battery charger with a dedicated USB charging path. Charger operation goes up to 13.2V, with a 16V absolute maximum, and it supports 4A on a single charge path or up to 10A when paired with an SMB1393 in a dual-path setup. That range covers everything from standard wall chargers to higher-wattage fast chargers without the board tripping into a fault state.USB Type-C support follows Rev. 1.4 of the spec, and USB Power Delivery follows Rev. 3.0 — both matter when you're diagnosing a board that charges fine on one cable or brick but not another, since Type-C negotiation faults often trace back to this IC rather than the port itself. Quick Charge support spans Qualcomm's QC 2.0, 3.0, and 4.0 protocols, so boards that should fast-charge but sit at trickle speeds are worth checking here before you condemn the battery or the charging port.

Beyond charging, the PM7325-000 covers the board's LCD power path, including the WLED backlight driver and LCD bias power. That makes it relevant to two different fault categories that look unrelated on the surface: a phone with no charging response, and a phone that boots but shows a blank or dim screen. Both can trace back to this same chip, which is why it's worth ruling out early instead of jumping straight to the display assembly.For workshop use, this is a reballing job. You're pulling a faulted chip, cleaning the pads, and reballing a fresh PM7325-000 rather than reflowing the old one — chip-level power IC faults rarely resolve with hot air alone. Have your reballing kit, stencil, and microscope set up before you start, since the ball pitch on Qualcomm PMICs doesn't forgive misalignment.This is a genuine component, not a clone or a remarked chip, which matters more with power ICs than almost any other part on the board — a bad power IC can take the battery, charging port, or main PMIC down with it if the fault isn't isolated properly first. Confirm the fault with a proper diagnostic box or multimeter check on the charging lines before committing to a swap.Stock this alongside your other Snapdragon-side power ICs and UFS/eMMC tools if you're running a full-service repair bench — dead-board diagnosis on Qualcomm devices almost always touches PMIC, charging IC, and storage IC territory together, so having the reballing and testing chain ready saves you a second trip to the parts drawer mid-repair.
