Description
The NU2111A chip is directly responsible for negotiating with smart chargers (PD/PPS) and regulating the high-current and voltage flow to the S25 series battery. This IC is frequently damaged by the use of aftermarket cables or unregulated car chargers, power surges, or a short circuit caused by moisture in the Type-C port. Failure of this component results in a completely dead charging line, extremely slow charging speeds, or unstable current draw. Replacing this IC strictly restores the phone’s ability to safely negotiate with the charger and receive power at its original, rapid speed.
Technical Specifications & Features:
Exclusive Compatibility (S25 Series): Precision-engineered to perfectly match the logic boards of the entire modern Samsung Galaxy S25 lineup.
OEM Power Regulation: Guarantees highly precise and stable regulation of high current, safely protecting the battery from swelling and preserving its lifespan.
Resolves Phantom Charging: Directly fixes issues where the charging icon appears on the screen, but the battery percentage fails to actually increase.
Restores Fast Charging: Addresses the issue where the device is restricted to slow charging (5V) and fails to step up to high-voltage Fast/Super Fast charging protocols (9V/11V).
