Part Number: DRV8718-Q1
Hi,
I could not find in the data sheet of DRV8718-Q1 driver the information about internal watchdog timer behavior when a watchdog fault occurs.
The question is whether the internal watchdog timer is RESET after IC_STAT2.WD_FLT is cleared via IC_CTRL1.CLR_FLT = 1b or not.
Known behavior (no watchdog fault):
IC_CTRL2.WD_EN = 1b
IC_CTRL2.WD_FLT_M = 1b
IC_STAT2.WD_FLT = 0b -> No watchdog fault
Invert IC_CTRL2.WD_RST -> watchdog timer restart
Unknown behaviour (watchdog fault occurs):
IC_CTRL2.WD_EN = 1b
IC_CTRL2.WD_FLT_M = 1b
IC_STAT2.WD_FLT = 1b -> Watchdog fault occurs
Clear the watchdog fault: IC_STAT1.CLR_FLT = 1b
Is the watchdog timer restart or not?
