8.3.2 Daisy Chain Connection
Two or more DRV8860 devices may be connected together to use a single serial interface. The SDATOUT pin of
the first device in the chain is connected to the SDATIN pin of the next device. The SCLK, LATCH, RESET, and
nFAULT pins are connected together.
Timing diagrams are shown in Figure 7 and Figure 8 for the configuration of single devices, as well as two
devices in daisy-chain connection.
