Functional Breakdown
1. Power Distribution (DC-to-DC)
The PMI632-602 acts as a DC-to-DC converter. It takes the raw power from the battery (VBAT) or the USB charger (VBUS) and converts it into a stable system voltage known as VPH_PWR. This rail is the backbone of the phone, supplying power to nearly all other circuits, including the RF power amplifiers and primary PMIC.
2. Charging Management
One of its most critical roles is managing the Lithium-Ion battery charging cycle. It monitors the battery temperature (via the Thermistor/THERM pin) and regulates current flow to prevent overheating.2 It supports fast-charging capabilities, significantly reducing the time required to top up the device compared to older linear charging chips.
3. Display and Backlight Control
Unlike primary PMICs that focus on the CPU, the PMI632 series often includes dedicated drivers for the LCD/OLED display. It manages:
-
VDD_DISP: Positive and negative voltage rails for the screen.
-
Backlight: High-voltage boost for the LED string behind the LCD.
-
RGB/Flash: Integrated drivers for notification LEDs and the camera flash.
4. Safety and Protection
The chip is equipped with internal thermal sensors and over-voltage protection (OVP).3 If the chip detects a short circuit on the system rail or if the charging voltage exceeds safe limits, it will automatically shut down the power flow to protect the motherboard.
Application in Repair
In the mobile repair industry, the PMI632-602 is frequently replaced when a device is “Dead” (no power), failing to charge, or showing no display/backlight despite a working screen. Technicians typically use BGA reballing techniques to replace this chip, as the 72 solder balls underneath require precise heat and alignment.
