The PM8004 is a specialized Power Management Integrated Circuit (PMIC) manufactured by Qualcomm. It is frequently identified in the mobile repair industry as a “Small Power IC” or “Secondary PMIC.” Unlike the main PMIC that handles the entire phone’s power distribution, the PM8004 is designed to manage specific high-demand power rails, particularly for the application processor and charging subsystems.

Technical Overview
The PM8004 is a high-performance Buck Converter IC optimized for mobile devices. It primarily serves as a DC-to-DC step-down regulator. In modern smartphone architecture, the main PMIC often cannot handle the sheer volume of current required by the CPU/GPU and high-speed peripherals without generating excessive heat or requiring a massive footprint. The PM8004 is deployed as a companion chip to distribute this load. PM 8004 Original Mobile Phone IC
Key Specifications
-
Manufacturer: Qualcomm PM 8004 Original Mobile Phone IC
-
Package Type: WLNSP (Wafer Level Nano Scale Package) or BGA (Ball Grid Array). PM 8004 Original Mobile Phone IC
-
Pin Count: Typically features a high-density 63-ball or 40-pin configuration depending on the specific revision.
-
Input Voltage Range: Designed to operate within standard Li-ion battery ranges (approx. $3.2\text{V}$ to $4.4\text{V}$).
-
Function: Multichannel power distribution, voltage regulation, and buck conversion.
Core Functions in Mobile Devices
The PM8004 is critical for several hardware processes:
-
Voltage Regulation: It converts the raw battery voltage into stable, lower voltages (e.g., $1.1\text{V}$, $1.8\text{V}$, or $3.3\text{V}$) required by sensitive digital components.
-
Current Management: It manages high-current rails to ensure the processor receives “clean” power during intensive tasks like gaming or 4K video recording.
-
Thermal Protection: The IC includes internal thermal shutdown circuitry. If the chip detects excessive heat—common in power-intensive circuits—it will throttle or cut power to protect the motherboard.
-
Charging Logic: In many designs, such as the Samsung Galaxy S7, it acts as a secondary charging controller, assisting the main IC in managing fast-charging protocols.
Common Applications
The PM8004 is most famously associated with the Qualcomm Snapdragon 820 and 821 platforms. You will find this IC in several flagship-tier devices from that era, including:
-
Samsung: Galaxy S7, S7 Edge, and Note 7.
-
Xiaomi: Mi 5, Mi Note 2, and Mi Max.
-
Oppo/Vivo: R9s Plus, X7, and X9 series.
Repair and Troubleshooting
In the field of mobile forensics and repair, the PM8004 is a frequent “point of failure.” Because it handles high current, it is susceptible to damage from:
-
Short Circuits: Often caused by water damage or low-quality charging cables.
-
Overheating: Prolonged heavy use can lead to the solder balls beneath the IC cracking (dry joints).
Symptoms of a faulty PM8004 include:
-
Dead Phone: The device refuses to power on or shows $0.01\text{A} – 0.05\text{A}$ on a DC power supply.
-
Charging Issues: The phone detects the charger but the battery percentage does not increase.
-
Sudden Reboots: The device crashes when the CPU load increases.
Installation Note
Replacing the PM8004 requires professional BGA soldering skills. Since it is a WLNSP/BGA chip, it must be “reballed” with leaded or lead-free solder spheres and soldered using a hot air rework station at temperatures typically between 330°C and 350°C, depending on the flux and motherboard thickness.
