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

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 VPWR.

32. Time necessary for CSNS to be within ±5.0% of the targeted value (from HS voltage = 50% of VPWR 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.
