Description

The CPS4038 chip is responsible for managing the wireless charging and reverse wireless charging processes. It converts and regulates the electromagnetic energy received from the wireless charging coil into direct current, routing it safely to the main charging circuit. This IC is frequently damaged by the use of substandard, non-Qi compliant wireless charging pads, severe impacts, or excessive heat. Failure of this component completely disables the wireless charging feature and may cause power leakage. Replacing this IC safely restores the efficiency and stability of wireless power reception and transmission.

Technical Specifications & Features:

• Flagship Compatibility: Precision-engineered to perfectly match the logic boards of the Samsung Galaxy S23 Ultra, and the entire S24 and S25 lineups.

• OEM Performance: Guarantees precise regulation of wireless current to prevent thermal throttling and protect the battery and logic board from overvoltage.

• Reverse Charging Support: Fully restores the Wireless PowerShare feature for charging peripherals like earbuds and smartwatches directly from the phone.

• Resolves Thermal Leakage: Fixes extreme overheating issues caused by an internal short circuit within the wireless charging IC.
