DESCRIPTION

PWBS751 is the host controller which needs to work with PWBS331

Square wave BUS technology deliveries both of the DC power and signal data on only two wires. Through modulating the signal on DC power lines, it replaces the traditional separated communication lines and DC power lines, also it improve the reliability of communication to the highest possibility which ensures a best way to improve the EMC performance.

Square wave BUS transmits signal on two lines by full amplitude DC voltage pulse wave and receiving signal by current, which ensures a highest reliable communication result in industry field.

PWBS751 adapts to any type of the wires, and can work in any topology network with no polarity limit. That simplifies the engineering connection of BUS lines.

Besides the communication function, PWBS751 supports power management function which deliveries DC power, and provides fault diagnosis of the BUS lines.
