Key Functional Blocks
The PM7250B is not just a voltage regulator; it is a multi-functional power hub.
-
Advanced Battery Charging: Features a best-in-class 4 A switch-mode Li-ion charger. It is fully compliant with USB Type-C Rev 1.3 and USB Power Delivery (PD) 3.0.
-
Quick Charge Support: Native hardware support for Qualcomm Quick Charge 2.0, 3.0, and 4.0 technologies.
-
Fuel Gauge: Integrates a Qualcomm battery gauge that uses a hybrid of voltage and current-based sensing for highly accurate State-of-Charge (SoC) estimation, accounting for battery aging and temperature.
-
Output Rails: Includes multiple Low Drop-Out (LDO) regulators and Buck converters to provide stable voltages for $V_{CC}$ Core, $V_{CC}$ GPU, and 1.8V I/O rails.
-
Vibrator Driver: Includes a built-in driver for Eccentric Rotating Mass (ERM) haptic motors.
Application and Repair Context
The PM7250B is frequently found in devices powered by Snapdragon 7-series and 8-series chipsets. Common compatible models include the Xiaomi Redmi Note 12, Huawei Nova 11, and Honor 60.
In the repair industry, this IC is often replaced to fix the following issues:
-
Charging Failure: Phone not detecting charger or charging extremely slowly.
-
No Power: The device is “dead” due to a short circuit within the PMIC’s internal buck converters.
-
Fast Battery Drain: Leakage within the IC causing excessive standby power consumption.
Note for Technicians: Replacing the PM7250B requires professional micro-soldering skills. Since it is a BGA/FOWPSP package, it must be “reballed” or replaced using a hot air station set to approximately 260°C to 300°C depending on the PCB thickness and solder alloy used.
