Hi,
I have configured three DRV8806 in daisy chain connected to a SPI module of my MCU. The clock , the latch and data IN seems to act correctly. Enable signal is active and reset signal is inactive. For a unknown reason, I'm not able to change the outputs state of those drivers.
I want to know if an open circuit fault can stop the three drivers to operate correctly ?
When configured in daisy chain, it's necessary to put a pull-up resistor on SDOUT pin for each DRV8806?
I attached the schematic that I made for my application to this message :
Thank you,
