DYNAMIC ELECTRICAL CHARACTERISTICS
Table 4. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 6.0V ≤ V_PWR ≤ 20V, 3.0V ≤ V_DD ≤ 5.5V, - 40°C ≤ T_A ≤ 125°C, GND = 0V, unless
otherwise noted. Typical values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions, unless
otherwise noted.

Notes
26. Time necessary to report the fault to FS pin.
27. 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
28. Time necessary for the CSNS to be with ±5% of the targeted value.
29. 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.
