The PM8005 is a critical Power Management Integrated Circuit (PMIC) developed by Qualcomm, primarily designed for high-end smartphones and mobile devices. In the complex ecosystem of a mobile motherboard, the PM8005 acts as a “secondary” or “auxiliary” power regulator, working in tandem with a primary PMIC (like the PM8998) to manage the energy demands of specific high-performance subsystems.
Core Function and Purpose
The primary role of the PM8005 is to convert the raw voltage from the Lithium-ion battery into precise, stable, and clean DC voltages required by various internal components. While a main PMIC handles general system power, the PM8005 is often dedicated to “heavy lifting” tasks, such as powering the CPU cores, GPU, or Baseband processors.
By offloading these specific power rails to a secondary IC, manufacturers can reduce the thermal load on the main processor area and improve overall electrical efficiency. This is vital for modern devices that require rapid bursts of power for gaming, 4K video recording, or 5G/LTE data processing.

Application in Mobile Devices
You will most commonly find the PM8005 in flagship devices from the 2017–2019 era, specifically within the Samsung Galaxy S8, S8+, Note 8, and Note 9 series (often the Snapdragon variants). It is also used in other high-performance devices like the Xiaomi Mi 6. PM 8005 Mobile Phone IC
In these devices, the PM8005 is often referred to by technicians as the “Small Power IC” or “Baseband Power IC.” If this chip fails, the device may exhibit several “no-fix” symptoms:
-
No Power/Dead Boot: The phone refuses to turn on because a vital CPU rail isn’t receiving voltage. PM 8005 Mobile Phone IC
-
Short Circuit: A damaged PM8005 can cause a “full short” on the VCC_MAIN or battery line, leading to rapid battery drain or heating. PM 8005 Mobile Phone IC
-
Radio/Signal Issues: Since it often powers the baseband, a fault can lead to “No Service” or IMEI-related software errors. PM 8005 Mobile Phone IC
Repair and Installation
Because the PM8005 uses a BGA (Ball Grid Array) mounting style, it is not a “plug-and-play” part. Replacing it requires professional micro-soldering equipment, including a hot air rework station, high-quality flux, and often a reballing stencil to prep the tiny solder spheres on the underside of the chip.
