Notes

28.

Time necessary to report the fault to FSB 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 FSB 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 time-out delay measured from the rising edge of RSTB, to HS[0,1] output state depend on the corresponding

input command.
