DYNAMIC ELECTRICAL CHARACTERISTICS
Table 5. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 6.0 V ≤ VPWR ≤ 20 V, 3.0 V ≤ VDD ≤ 5.5 V, -40 °C ≤ TA ≤ 125 °C, GND = 0 V, unless
otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions, unless
otherwise noted.

Notes
28. Time necessary to report the fault to FS pin.
29. 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 VPWR
30. Time necessary for CSNS to be within ±5% of the targeted value (from HS voltage = 50% of VPWR to ±5% of the targeted CSNS value).
31. 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.
