The PM 820 is a specialized Power Management Integrated Circuit (PMIC) predominantly used in mid-range mobile devices and tablet architectures. It serves as the “heart” of the device’s power distribution system, regulating voltage from the battery to various components like the CPU, GPU, display, and camera.
Note: While there is a high-precision industrial power meter also named the “PM820” (manufactured by Schneider Electric), the mobile phone version is a BGA (Ball Grid Array) semiconductor chip designed for cellular hardware.

Key Functional Modules
To understand how the PM 820 operates within a smartphone, it is helpful to look at its internal logical architecture:
1. Switching Regulators (Buck/Boost)
The PM 820 converts the fluctuating battery voltage into stable, low voltages required by high-drain components. For example, it provides the $V_{core}$ for the processor, which often operates at levels around $1.0V$ to $1.2V$. Switching regulators are used here because they minimize heat generation compared to linear regulators.
2. Low Dropout Regulators (LDOs)
For sensitive components like the RF (Radio Frequency) section or the Audio Codec, the PM 820 uses LDOs. While less efficient than Buck regulators, LDOs provide “cleaner” power with significantly less electrical noise, ensuring that signal processing remains clear.
3. Battery Management & Charging
The PM 820 often handles the initial stages of charging. It monitors the battery’s State of Charge (SoC) and temperature, ensuring that the charging current is reduced as the battery reaches its upper voltage limit to prevent swelling or fires. PM 820 ORIGINAL Mobile Phone IC
4. Real-Time Clock (RTC) Support
Even when your phone is “off,” the PM 820 keeps a tiny portion of its circuitry alive to power the internal clock. This ensures your phone always displays the correct time and date upon reboot.
Physical and Installation Characteristics
Since the PM 820 is a BGA chip, its underside is covered in microscopic solder balls rather than traditional pins. PM 820 ORIGINAL Mobile Phone IC
-
Pin Configuration: The balls are arranged in a grid. Replacing this IC requires “reballing” or using a pre-balled original chip. PM 820 ORIGINAL Mobile Phone IC
-
Thermal Dissipation: The chip uses the PCB (Printed Circuit Board) as a heat sink. During heavy tasks like gaming or fast charging, the PM 820 can become quite warm, and its internal thermal sensors will trigger a “thermal shutdown” if it exceeds safe limits.
-
Repair Note: Because it is a BGA component, specialized tools like a Hot Air Rework Station and high-quality flux are required for installation. PM 820 ORIGINAL Mobile Phone IC
Common Fault Symptoms
When a PM 820 IC fails, the device usually exhibits one of the following “Dead” or “Power-related” symptoms:
-
No Power: The device does not respond to the power button, and no charging icon appears. PM 820 ORIGINAL Mobile Phone IC
-
Short Circuit: The device consumes high current (detected via a DC Power Supply) even before the power button is pressed. PM 820 ORIGINAL Mobile Phone IC
-
Hanging/Freezing: Unstable voltages to the CPU can cause the operating system to crash randomly. PM 820 ORIGINAL Mobile Phone IC
-
Charging Issues: The device may show it is charging but the battery percentage never increases (“Fake Charging”). PM 820 ORIGINAL Mobile Phone IC
Compatibility and Usage
The PM 820 is frequently paired with specific processor families (often Marvell or older Qualcomm LTE platforms). It is famously found in:
-
Samsung Tablets: Tab 3 Lite (T111), Tab 4 7.0 (T230/T231). PM 820 ORIGINAL Mobile Phone IC
-
Samsung Phones: Galaxy S3 Mini Value Edition (I8200). PM 820 ORIGINAL Mobile Phone IC
