Charging complaints are one of the most common jobs that land on a GSM repair bench, and on the Samsung Galaxy Tab 3 7.0 series, the 358S IC sits right at the center of that fault line. This chip controls charging current regulation and USB signal switching for the tablet, and it's mounted at board position U506 on the T210 and T211 motherboards. When a customer brings in a tablet that shows "charging" on the screen but the battery percentage never climbs, or the tablet only charges when the cable is wiggled at a certain angle, this IC is one of the first components you check before moving on to the charging port or battery itself.
You already know the drill on this kind of dead-after-flash or fake-charging case. First rule out a bad charging port or a worn-out cable, then check the battery health, and if both test fine, the fault usually traces back to this IC or the trace feeding it. A multimeter check on the input and output lines around U506 will often confirm whether the chip has failed or whether you're dealing with a lifted trace or a jumper issue instead. If the IC has gone bad from moisture damage, a static short, or age, direct replacement is the fix, and there's no workaround for it once the chip itself is confirmed faulty.
Replacing the 358S follows the same reballing and hot air process you use across the board on fine-pitch charging ICs. Cover the surrounding components with heat-insulation tape, apply flux directly on the chip, and lift it with your hot air station without pushing past 350°C to avoid damaging the pads underneath. Clean the footprint thoroughly with flux and a fine tip before placing the new IC, then reflow with steady heat and check alignment under your microscope before powering the board back on. Rushing this step is where most technicians end up with a board that still won't charge even after the "repair," so take the extra thirty seconds to confirm the chip sat flat before you move to testing.
Genuine 358S chips matter here more than most people think. Counterfeit or recycled ICs from unverified sources fail fast, sometimes within days of the repair, and that comes straight back to your shop as a comeback job that eats into your margin and your reputation. Sourcing a verified, tested chip up front means fewer repeat visits and a customer who trusts your shop the next time their device acts up.
This part is compatible with the Samsung Galaxy Tab 3 7.0 series carrying model numbers T210, T211, and T215, and it's the same charging and USB control function whether the board came in as a WiFi-only or 3G variant of that lineup. Keep a few of these in your parts drawer alongside your usual charging port and battery stock, since Tab 3 charging faults still show up regularly given how many of these tablets are still in daily use across Pakistan.
For technicians running a busy repair counter, having this IC on hand means a same-day turnaround on Tab 3 charging complaints instead of telling the customer to come back next week. Pair it with a good flux paste, a fine hot air nozzle, and a steady hand under the microscope, and this becomes a routine fifteen-minute board job rather than a guessing game.
