Part Number:DRV11873
DRV11873 can not start and spin up the BLDC in small chances, only removing and reconnect the power can fix this.
When this issue happens, RD, FG pin is pulled high, CPN pin is pulled low, U V W COM pins are in DC voltage.
RD pulled low should be indicating a lock protection? What causes this situation?
When motor is running as expected, FG output frequency is 150Hz.
