Samsung S9 Schematic Diagram Extra Quality [ Exclusive × 2027 ]

Sites like Mobile-Manuals often host PDF versions of Galaxy S-series schematics.

Samsung engineers placed hundreds of exposed copper dots on the S9 board labeled TP101 , TP204 , etc. The schematic tells you the exact voltage and waveform you should see at that test point. This is invaluable for diagnosis with a multimeter or oscilloscope.

The battery voltage enters through the battery FPC connector. It passes through the primary protection circuit and enters the Main Power Management IC (PMIC). This primary rail distributes raw battery power to high-power components like the audio amplifier and RF power amplifiers. The Main PMICs (S515 / MAX77705)

Primary PMIC (e.g., Samsung S2MU005) and Secondary PMIC. Key Signals: VBATcap V sub cap B cap A cap T end-sub (Battery voltage), VPH_PWRcap V sub cap P cap H _ cap P cap W cap R end-sub (Main power line). 2. Processor and Memory (CPU/AP) samsung s9 schematic diagram
