The SC2723M is a Power Management Integrated Circuit manufactured by Spreadtrum, now part of UNISOC, and it belongs to the SC27xx PMIC family used across a wide range of Samsung entry-level and mid-range smartphones. On the motherboard, this chip sits at the center of power distribution, taking voltage from the battery and regulating it out to the CPU, memory, RF sections, and peripheral circuits. If you've ever pulled a Galaxy J2 or J3 board with a dead phone complaint and found zero current draw on your DC power supply, the SC2723M is one of the first ICs you check.Inside the chip, six functional blocks work together. DCDC converters step down battery voltage to feed the processor and memory modules. LDOs (low-dropout regulators) supply cleaner, lower-current rails to sensitive internal and external circuits. A battery management system handles charging control and fuel gauge readings, which is why boards with SC2723M faults often show up as charging issues — the phone plugs in but doesn't charge, or the battery percentage reads incorrectly. The chip also carries an integrated audio codec, so display problems aren't the only symptom category here; some SC2723M failures present as no sound or distorted audio. Rounding out the design, the IC manages user interface functions like status LED and flash control, plus core IC-level functions such as power on/off sequencing and RTC (real-time clock).For a Pakistani GSM technician working J-series repairs daily, the SC2723M shows up most often on three device families: the Galaxy J2 (SM-J210/J210F), the Galaxy J3 (SM-J320/J320F/J320H), and the smaller J1 Mini Prime (SM-J106) and J1 Ace (SM-J111F) boards. All four share the same PMIC footprint and port marking, which is one reason this IC stays in stock at nearly every GSM parts counter — it covers a huge share of the J-series repair volume that comes through Pakistani service centers.Common failure patterns that point to this IC include a board that's completely dead after a bad flash attempt, a board stuck at hang on logo with no further boot progress, inconsistent or failing charging behavior even after a charging port replacement, and random reboots or shutdowns tied to unstable power delivery. Before condemning the PMIC, check for shorted rails and confirm the battery connector and charging IC aren't the actual fault — but once those are ruled out, IC change on the SC2723M often brings a dead board back to life.This is a BGA-packaged component, which means it needs proper reballing and a hot air rework station set to the correct temperature profile for SPRD-series PMICs — overheating the pads is a common cause of repeat failures after IC change. A stencil matched to the SC2723M's ball pattern makes reballing far more consistent than freehand paste application, and a fixture that holds the board flat during reflow reduces the risk of tombstoning or bridging on this pitch.Because the SC2723M handles so many core functions in one package, a proper diagnosis before jumper lagana or replacement saves time on the bench. Confirm short circuits with a thermal camera or your multimeter's diode mode first, then move to IC replacement once the fault is isolated to the PMIC itself. For repair shops running high J-series volume, keeping a few of these ICs in stock alongside your reballing stencils and flux keeps turnaround time down on one of the most common Samsung repair jobs on the market.
