MT6372CP IC

Product Details
Product Details:

- Part Number: MT6372CP (Marking: 6372CP / MT6372CP)

- Manufacturer: MediaTek Inc. (MTK)

- Function: Secondary Power Management Integrated Circuit (Sub-PMIC / Companion Voltage Regulator)

- Internal Architecture: Synchronous Buck Step-Down Converters & Multiple High-PSRR Low-Dropout (LDO) Linear Regulators

- Communication / Bus Interface: MediaTek SPMI / I2C Bus control synchronized with the primary application processor

- Protection Circuits: Integrated Over-Voltage (OVP), Over-Current (OCP), and Thermal Shutdown (OTP)

- Package Type: Fine-Pitch BGA (Ball Grid Array) / WLCSP

- Mounting Type: Surface Mount Technology (SMD BGA Soldering / Reballing)

Usage:

- Auxiliary Voltage Rail Regulation: Works alongside the main PMIC to supply dedicated, clean power rails to camera modules, display panel logic, audio circuits, and peripheral sensors.

- Coordinated Power Sequencing: Coordinates startup, deep-sleep, and wake-up transitions in sync with the primary PMIC and application processor.

- Target Devices:

* Oppo: Oppo F15, Oppo A91, Oppo A8, Oppo A9 (2020)

* Honor / Huawei: Honor V30 Pro / Glory V30 Pro

* Meizu: Meizu Pro 7 series

* Other smartphones utilizing MediaTek Helio P-series (e.g., MT6771 / P60 / P70) and related companion layouts.

- Common Fault Symptoms & Motherboard Repair:

* Dead Phone (No Power / No Boot): A short-to-ground on auxiliary rails driven by MT6372CP locks down the primary PMIC startup sequence, preventing the phone from turning on.

* Hang on Logo / Boot Loop: Unstable voltage delivery to critical peripherals (like camera or sensor rails) causes the kernel to fail during device bootup.

* Thermal Heating / High Current Leakage: Noticeable heat generation around the secondary PMIC area when connected to a DC bench power supply.
