Notes
30. Time necessary to report the fault to FSB pin.
31. Time necessary to switch-off the output in case of OT, or OC, or SC, or UV fault detection (from negative edge of FSB pin to HS
voltage
= 50% of V
PWR
.
32. Time necessary for CSNS to be within ±5.0% of the targeted value (from HS voltage = 50% of V
PWR
to ±5.0% of the targeted CSNS
value).
33. 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.
