Usage:
- Used as the primary battery charging management and system power-path controller in slim smartphones and compact mobile devices (compatible with Huawei, Oppo, Vivo, Infinix, Tecno, and other Android motherboards).
- Features Narrow VDC (NVDC) power-path architecture to turn the device on immediately upon connecting a charger, even if the battery is fully drained, defective, or disconnected.
- Hardware D+/D- lines automatically detect the input charger type to set the correct input current limit without host processor intervention.
- Used in motherboard repair to fix dead charging lines, fake charging (charging icon shows but battery percentage does not rise), slow charging, short circuits on VBUS/PMID/SYS lines, and OTG supply failures.
