SN2611A0 Charging IC for iPhone 11/11 Pro/11 Pro Max

When a customer brings in an iPhone 11 series phone with a charging complaint, the SN2611A0 is usually one of the first ICs you check after ruling out the charging port and battery. This chip sits at position U3300 on the board and controls how USB power gets distributed once it enters the phone. Technicians in the trade call it the Tigris IC, and you'll hear that name on group chats and supplier listings just as often as the part number itself.Charging faults on the iPhone 11 series show up in a few familiar patterns. Sometimes the phone shows the charging symbol but the percentage never moves. Sometimes it charges only when you wiggle the cable at a certain angle, which technicians often blame on the port first, only to find the real fault sits on this IC. Other times the phone charges fine on a wall adapter but not through a PC, or it charges slow no matter what charger you use. A damaged or corroded SN2611A0 causes all of these symptoms, and liquid damage is the most common reason it fails, since this area of the board sits close to the charging port and takes the first hit from any water ingress.Working with this IC means working with BGA soldering. You need a hot air station set to a controlled temperature, flux, and either a stencil or your own reballing skill to get the balls seated correctly. Rushing the reflow or overheating the pads is the fastest way to lift a trace on this board, so this is not a beginner job — go in with your temperature dialed in and your board preheated. After placement, always check continuity on the surrounding passives before you close the phone up, since a cracked IC is often just one symptom of a wider liquid damage pattern.This chip fits directly into the eMMC and diagnostics side of your repair workflow too. If a phone comes in dead after flash or hanging on the Apple logo, and your first checks rule out software, charging circuit faults like this one are next on the list, because the phone may simply not be getting enough power to boot properly. Pair this IC replacement with a proper board clean under isopropyl alcohol and a microscope inspection for corrosion on nearby components before you commit to soldering — a clean board saves you a comeback repair.Stock this IC alongside your other iPhone 11 series power components, since techs working liquid-damage boards usually need more than one chip from the same area in a single job. Keep a few in stock rather than ordering one at a time, since board-level repair on iPhone 11 units remains steady work in most repair shops. This part ships as a bare IC only — no adapter board or tool included — so it's meant for technicians who already run a hot air rework station and know how to handle micro-soldering on modern iPhone boards.
