The PM6150A (typically the PM6150A-102 variant) is a high-performance Power Management Integrated Circuit (PMIC) designed by Qualcomm. It is a cornerstone of modern mid-to-high-tier smartphone hardware, particularly those utilizing Snapdragon 600 and 700 series chipsets. PM 6150A Mobile Phone IC
Unlike standard power ICs that handle simple regulation, the PM6150A acts as a Companion PMIC. It works alongside a primary PMIC (like the PM6150) to manage specific high-drain or precision rails such as the CPU/GPU core, memory interfaces, and camera sensors. PM 6150A Mobile Phone IC

Key Functional Roles
The PM6150A is specialized for “heavy lifting” in the power architecture. Its primary roles include:
-
Processor Voltage Scaling: It provides the VDD_CORE and VDD_MIF rails. These are dynamic voltages that change based on whether your phone is idling or running a heavy game.
-
Camera & Display Support: It often manages the high-precision power required for image sensors and display driver logic (VCC_LCD).
-
Energy Efficiency: By offloading specific rails from the main PMIC, it reduces localized heat on the motherboard and improves battery longevity through efficient DC-DC conversion.
Compatibility and Deployment
The PM6150A is a versatile chip found across various brands due to its integration with Qualcomm reference designs.
Supported Platforms
It is most commonly found in devices using the following platforms:
-
Qualcomm Snapdragon 675 / 710 / 712 / 730G
-
Samsung Galaxy A Series (e.g., A70, A60)
-
Xiaomi Redmi Note Series (e.g., Note 7 Pro)
-
Vivo & Oppo Mid-tier models
Troubleshooting & Failure Symptoms
Because it sits at the heart of the power distribution, a faulty PM6150A usually results in a “Dead Board” scenario. Common symptoms include:
-
Zero Boot: The phone does not respond to the power button.
-
Short Circuit: The motherboard shows a high current draw on a DC Power Supply immediately upon connection.
-
Hanging on Logo: If the rails for memory or the GPU are unstable, the device may freeze during the boot sequence.
Maintenance & Repair Notes
Note: Replacing this IC requires professional micro-soldering skills. The PM6150A is a BGA chip, meaning it has tiny solder balls underneath that must be perfectly aligned with the motherboard pads.
-
Reballing: Use a 0.12mm stencil for the best results when re-applying solder balls.
-
Heat Sensitivity: Use a rework station set between 330°C and 350°C with medium airflow to avoid damaging the internal silicon die or surrounding components.
