98611 Charging IC

Samsung G7200, G7508Q, and J7008 boards use the 98611 IC to manage two jobs at once: controlling charging current into the battery and driving the backlight/light control circuit on the display side. That dual role is exactly why this chip shows up so often on the repair bench — a fault here doesn't just kill charging, it can also take the display light down with it, and technicians frequently misread the symptom as a screen fault before tracing it back to this IC.On a real repair bench in Pakistan, the 98611 usually comes up in three situations. First, dead after flash — the phone was working, got flashed or software marna hoyi, and now it won't charge or boot past the logo. Second, charging issue where the phone shows "charging" on screen but the battery percentage never moves, or it charges painfully slow. Third, a light control problem where backlight flickers, dims randomly, or the display goes dark while the rest of the board still powers up fine. In all three cases, testing the 98611 pins with a multimeter for shorts or open circuits, or swapping in a known-good chip, is a faster diagnostic route than chasing software resets first.Replacing this IC is a board-level reballing job, not a beginner task. You need a hot air station set to the correct profile for a 30-pin package, flux, a stencil sized for the 98611 footprint, and a steady hand — overheating adjacent components on a tightly packed Samsung board is the most common mistake technicians make on this repair. Clean the pad thoroughly after removing the old IC, check for lifted pads or hairline board damage before reballing, and always test charging current and backlight function immediately after reflow, before closing up the phone.This IC ties directly into the broader PCB repair workflow for Samsung mid-range devices. It sits between the charging port circuit and the PMIC on one side, and the display driver/light control path on the other, so a technician diagnosing a "dead phone" on these models should treat 98611 as a checkpoint, not an afterthought. If a phone comes in with a jumper already placed near the charging IC area from a previous repair attempt, that's often a sign the 98611 was suspected before and worth checking again under microscope for cold joints or hairline cracks.Stocking this IC makes sense for any shop that regularly handles Samsung G7200, G7508Q, or J7008 units, since it's a recurring failure point rather than a rare fault. Pairing it with the 3632A light control IC and S2DOS04 display IC — the two chips commonly replaced alongside it on the same board family — covers most charging-and-display combination faults technicians see on these models. Buy it as a bench-stock item alongside your existing IC tray rather than a one-off order, since repeat charging faults on these Samsung boards are common enough that having it on hand saves a same-day turnaround for your customer.For technicians running a UFS/eMMC and board-repair combined workflow, keep this IC alongside your reballing kit, PCB holder, and microscope setup — most 98611 replacements happen in the same repair session as a general board inspection, so having the part ready avoids a second teardown.
