PM660 002 Power iC

Open up a Redmi Note 7 or a Vivo X21 with a dead phone complaint and there's a good chance the PM660-002 sits at the center of the fault. Qualcomm designed this PMIC to handle the core power rails for Snapdragon 636, 660, and 710 chipsets — it controls battery charging logic, feeds regulated voltage to the CPU, RF, and display subsystems, and manages the power sequencing that lets the board boot in the first place. When this IC goes bad, you rarely get a clean symptom. It shows up as a completely dead board, a phone stuck at hang on logo, random reboots, or a device that draws current but never powers on.On the repair bench, this is a board-level component, not a plug-and-play accessory. You'll need hot air rework skills, a good preheater, and either a stencil or laser-cut template for reballing before you drop this IC back onto the board. Technicians dealing with dead after flash situations, where a device won't come back even after a fresh software flash, often trace the fault back to a failed PMIC rather than a corrupted flash. If the phone shows zero current draw or the current jumps abnormally on your power supply box, that's your cue to pull and test the power IC before you waste time on software marna.This part matches the PM660-002 marking used in Xiaomi's Mi A2, Mi Max 3, Redmi Note 5, Redmi Note 6 Pro, and Redmi Note 7, as well as Oppo's R11 and R11S, and Vivo's X20 Plus and X21. All of these share the same Snapdragon 636/660-class platform architecture, which is why the same PMIC part number carries across brands. Before you commit to a reball, confirm the exact IC marking on the board against the schematic for that specific model, since board revisions sometimes swap PMIC variants even within the same phone series.Sourcing a reliable PM660-002 matters more than most technicians assume. A counterfeit or recycled chip with worn balls or contaminated pads causes intermittent charging issue complaints that look like a software fault, sending you down the wrong troubleshooting path. This listing is a fresh IC, tested before packing, meant to go straight into your reballing workflow without extra prep.In a typical repair sequence, this IC comes into play after you've ruled out the charging port, battery, and short-circuit faults on the board using your multimeter and power supply box. Once you've confirmed the PMIC rail itself is the problem — no output on the LDO lines feeding the CPU or RF sections — this is the exact replacement to reball onto the board. Pair it with a hot air station capable of controlled, even heat distribution, since PMIC pads are dense and prone to shifting if the reflow isn't even.Stock this IC alongside your other Snapdragon-platform power ICs if you handle a steady flow of Xiaomi, Oppo, and Vivo repairs. It's a recurring point of failure across these device families, especially on boards that have seen liquid exposure or a bad charging adapter history.
