The SBT6620 is an intelligent and reliable Synchronous Serial Interface (SPI-like) controlled, eight-channel peripheral load driver and input monitor IC. The status of each of the I/O pins can always be read and can optionally be configured as an output. When configured as an output, each I/O pin is internally current limited and can sink or source current. The output voltage and input voltage threshold on the I/O pins scales to the voltage input so that voltages other than the controller Vdd can be used and allows the IC to monitor higher voltages, like a high voltage AC, or DC rail. This feature contributes to system versatility and reliability.
