Daisy Chain Connection
Two or more DRV8806 devices may be connected together to use a single serial interface. The DOUT pin of the
first device in the chain is connected to the DIN pin of the next device. The SCLK, LATCH, RESET, and nFAULT
pins are connected together.
Timing diagrams are shown on the following pages for the configuration of single devices, as well as two devices
in daisy-chain connection.
