描述 Description

The CS4968 is a wireless power controller to control the power transferring according Qi standard. The CS4968 has integrated all controlling functions to minimize the external components required to implement a wireless power transmitting system. The CS4968 supports multiple Qi specified Type A Power Transmitter designs including A6 and A11. The integrated communication channel is compatible with the WPC 1.2.2 standard.
The CS4968 features Dynamic PowerManagement (DPM) working with a 5V system to seamlessly obtain the maximum power without stressing the power supplier which has limited current capability. The CS4968 monitors safety issues such as over current, over voltage, over temperature and presence of a foreign object, should any safety hazards develop, CS4968 aborts the power transfering.
The CS4968 is available in an area saving 48-pin,6-mmx 6-mm QFN package and operates over a temperature range from-40°℃ to 85℃.
