Key Functional Modules
1. Advanced Voltage Regulation
The PM660-001-1 utilizes a combination of Buck Converters (for high efficiency at high currents) and Low-Dropout Regulators (LDOs) (for noise-sensitive components like cameras and audio). This allows the device to step down battery voltage to the very specific levels required by 14nm or 10nm processors, often as low as $0.8V$. PM 660-001-1 Original Mobile Phone IC
2. Battery Management & Charging
One of its standout features is the integration of the charging logic. It supports high-efficiency “Switching Chargers.” PM 660-001-1 Original Mobile Phone IC
-
Quick Charge Support: It manages the negotiation between the phone and the wall adapter to pull higher wattage safely. PM 660-001-1 Original Mobile Phone IC
-
Fuel Gauge: It contains precise circuitry to monitor the battery’s State of Charge (SoC) and State of Health (SoH), ensuring your percentage indicator is accurate. PM 660-001-1 Original Mobile Phone IC
3. Peripheral Power Control
Beyond the CPU, this IC manages:
-
Display Power: Providing the bias voltages for LCD or AMOLED panels. PM 660-001-1 Original Mobile Phone IC
-
Haptics: Driving the vibration motor. PM 660-001-1 Original Mobile Phone IC
-
Audio: Often houses basic codec support or power for external audio amplifiers. PM 660-001-1 Original Mobile Phone IC
Implementation & Pinout Logic
The PM660 series uses an SPMI interface, which is a high-speed bi-directional bus. This allows the main Application Processor (AP) to tell the PMIC to “ramp up” voltage instantly when you open a heavy app (like a game) or “throttle down” when the phone is idling to save battery.

Environmental & Physical Specs
-
Operating Temperature: $-40°C$ to $+125°C$ (Industrial grade durability).
-
Form Factor: The WLCSP design is extremely thin, allowing it to fit into the cramped, multi-layered PCBs found in modern “slim” smartphones.
Common Usage Scenarios
While primarily found in smartphones like the Xiaomi Mi Note 3 or Nokia 7 Plus, the PM660-001-1 is also used in:
-
IoT Gateways: Where power efficiency is critical for always-on connectivity.
-
Tablets: Handling the larger current draws required by bigger screens.
-
Embedded Systems: High-end robotics controllers that use Snapdragon SoMs (System on Modules).
Note on Repairability: Because this is a BGA (Ball Grid Array) component, replacing a faulty PM660-001-1 requires professional microsoldering tools and a reballing stencil. It is highly sensitive to ESD (Electrostatic Discharge).
Summary of Efficiency
The PM660-001-1 is engineered to minimize “Quiescent Current”—the power the chip consumes just to stay awake. By keeping this value in the micro-amp range, it significantly extends the standby time of mobile devices.
