Technical Specifications
- IC Classification: Fast-Charge Single-Cell Dual-Phase Switched Capacitor (Swit Cap) IC.
- Package Type: BGA-36 (Ball Grid Array with 36 pins), Surface Mount Device (SMD).
- Charging Architecture: Dual-phase switched capacitor technology. This layout allows for high current transfer at very high efficiency, cutting heat generation inside the phone by up to 50% compared to traditional buck regulators.
- Safety Protocols: Integrated overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown/overheating mitigation.
Primary Function
The IC is deployed alongside the primary PMIC (Power Management IC) to regulate and safely accelerate battery charging. By managing high current directly to a single-cell Li-ion/Li-Po battery, it enables modern high-speed charging without causing severe thermal throttling.
Common Device Compatibility
This IC is widely utilized across several major smartphone brands for their midrange and flagship fast-charging configurations:
- Infinix: Widely used in the Infinix Note 12i charging circuit.
- Honor / Huawei: Deployed in devices like the Honor 90, Enjoy 70 Pro, Enjoy 60X, and Huawei Mate 60 series.
