FSA7830: 8-Channel Voltage MUX with Integrated Voltage Divider and OVP

The FSA7830 is an 8-Channel, low-power Voltage MUX.     It integrates 8 analog switches for input voltage selection, and voltage dividers to provide 1/3, 2/3 fraction of selected voltage. With another 3 analog switches, FSA7830 provides feasibility to choose 1/3, 2/3 or 1 times of selected voltage. FSA7830 also contains output buffer to enhance driving capability. It features over-voltage protection to ensure output less than 2 V; interrupt will be alerted at the same time. FSA7830 supports 1.8 V I2C interface to communicate with processor, and 2 address pins to provide multi-chip solution.
