Notes
32. Time necessary to report the fault to FS pin.
33. Time necessary to switch-off the output in case of OT or OC or SC or UV fault detection (from negative edge of FS pin to HS voltage = 50% of V
PWR
34. Time necessary for CSNS to be within ±5% of the targeted value (from HS voltage = 50% of V
PWR
to ±5% of the targeted CSNS value).
35. For FSI open, the Watchdog timeout delay measured from the rising edge of RST, to HS[0,2] output state depend on the corresponding input
command.
