The SPU16 is a specialized Power Management Integrated Circuit (PMIC) designed primarily for modern mobile devices, including the Samsung Galaxy series and select iOS devices (often cross-referenced as PM6450 in certain schematics).1 It serves as a high-efficiency voltage regulator and power distribution hub, managing critical rails for the CPU, GPU, and battery charging systems.2
Core Functionality
The SPU16 is a “drop-in” successor to the SPU15 and SPU15Q series.3 It is engineered to handle the high-current demands of mobile processors while maintaining a small footprint. Its primary role is to convert the battery’s fluctuating voltage into stable, low-noise power for sensitive internal components. SPU16 Mobile Phone IC`

Pin Configuration & Layout
In standard mobile repair contexts, the SPU16 utilizes a 6-pin or 16-pin layout depending on the specific board implementation. The most common 6-pin diagnostic layout is as follows:
-
EN (Enable): High-active logic to wake the IC.4
-
VIN (Input): Main power entry from the battery or charging port.
-
SW (Switching): Connection to the external inductor for buck conversion.
-
GND (Ground): Common reference point.5
-
FB (Feedback): Monitors output voltage for closed-loop regulation.
-
OUT/NC: Regulated output or No Connection depending on the PCB trace.
Key Performance Features
-
Enhanced Stability: Unlike its predecessors, the SPU16 features tighter tolerance on the bandgap reference circuit, which prevents “false low-battery” shutdowns.6
-
Pulse Skip Mode: This allows the IC to remain highly efficient even when the phone is in a deep sleep or idle state by reducing switching cycles.
-
Integrated Protections: It includes built-in Over-Current Protection (OCP) and Over-Voltage Protection (OVP) to safeguard the application processor from power surges.7
Installation & Repair Notes
Replacing an SPU16 requires professional BGA/SMD soldering skills.8 Because these chips are often located near the CPU or NAND flash, heat management is critical.9
-
Recommended Air Temp: $330^\circ\text{C}$ to $350^\circ\text{C}$ (depending on the station).
-
Failure Symptoms: Device won’t turn on, “dead” short on the primary power rail (10$V_{bat}$), or charging stopping abruptly at a specific percentage.11
