Description 
GX28E17 is a communication bridge that converts 1-Wire slave to I2C host. The communication data is transmitted serially through the 1-Wire protocol and converted into the corresponding I2C output. The 1-Wire protocol only requires a single signal line, which can effectively save GPIO resources.  
The GX28E17 has a ROM ID used as a node address in the 1-Wire bus, ensuring that the chip can coexist with other devices in the 1-Wire bus and can be accessed separately without affecting other devices.  
The GX28E17 flexibly supports different 1-Wire and I2C speed modes, making it suitable for various complex I2C slave scenarios such as display controllers, analog-to-digital converters, digital to analog converters, I2C sensors, and more.  
GX28E17 supports low-power application scenarios. Sleep mode can be activated through the Sleep pin or 1-Wire command, reducing power consumption to 0.3uA. The independent Sleep pin, Wakeup pin, and Awake pin can flexibly meet user needs. The Awake pin can be used to control remote power supply.
