Functional Pin Groups
-
VBAT / VPH_PWR: Main battery and system power inputs. PM 8916 Original Mobile Phone IC
-
VREG_S1/S2/S3/S4: Buck regulator outputs for high-power demands. PM 8916 Original Mobile Phone IC
-
VREG_L1 to L20: LDO outputs for clean, low-current power. PM 8916 Original Mobile Phone IC
-
CHG_IN: Input from the USB port/charger (typically supports up to 6.2V).
-
MPPs (Multi-Purpose Pins): Can be configured as GPIOs, ADCs, or current sinks. PM 8916 Original Mobile Phone IC
3. Integrated Sub-Systems
The PM8916 is more than just a voltage regulator; it contains several sub-processors and controllers:
-
Battery Management (BMS): Includes an integrated Fuel Gauge that uses an ADC (Analog-to-Digital Converter) to monitor battery voltage, current, and temperature (via NTC thermistor) for accurate percentage reporting.
-
Charging Control: Features an internal linear battery charger with over-voltage protection (OVP) and JEITA-compliant thermal monitoring to ensure safe charging.
-
Audio Codec (Partial): In many Snapdragon 410 designs, the PM8916 houses basic audio processing circuitry to drive the earpiece, speaker, and microphones.
-
Control Interface: Uses the SPMI (System Power Management Interface) to communicate with the Snapdragon processor, allowing the CPU to dynamically adjust voltages (DVFS) to save power.
4. Key Performance Characteristics
| Parameter | Value / Range |
| Input Voltage (USB_IN) | 4.4V to 6.2V (Max 16V OVP) |
| Operating Temperature | -25°C to +85°C |
| Quiescent Current | Ultra-low in Deep Sleep modes |
| Protections | Thermal Shutdown, Over-Current (OCP), Under-Voltage (UVLO) |
| Clock Support | Integrated 32.768 kHz Sleep Clock driver |
5. Application and Repair Insights
For mobile technicians, the PM8916 is a common point of failure. Because it handles the primary power from the charger, it is susceptible to damage from faulty cables or power surges.
-
Common Symptoms of Failure: Device not turning on (Dead), no charging, “Short-circuit” on the motherboard, or the device getting stuck at a specific current draw (e.g., 0.05A) on a DC Power Supply.
-
Replacement Notes: When replacing, the “0VV” or “001” suffix usually indicates versioning. While often interchangeable in some circuits, it is best practice to match the exact original part number.
-
Soldering: Being a BGA chip, it requires professional hot-air rework stations and a specific BGA stencil for “reballing” if it is being moved from a donor board.
