DYNAMIC ELECTRICAL CHARACTERISTICS

Table 4. Dynamic Electrical Characteristics (continued)

Characteristics noted under conditions 6.0 V ≤ VPWR ≤ 27 V, 4.5 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

21. Turn-ON delay time measured from rising edge of any signal (IN[0:3], SCLK, CS) that would turn the output ON to VHS[0:3] = 0.5 V with

RL = 5.0 Ω resistive load.

22. Turn-OFF delay time measured from falling edge of any signal (IN[0:3], SCLK, CS) that would turn the output OFF to VHS[0:3] = VPWR-

0.5 V with RL = 5.0 Ω resistive load.

23. This logical bit is not defined. Do not use.

24. Time necessary for the CSNS to be with ±5% of the targeted value.

25. Watchdog timeout delay measured from the rising edge of WAKE or RST from a sleep state condition, to output turn-ON with the output

driven OFF and FSI floating. The values shown are for WDR setting of [00]. The accuracy of t WDTO is consistent for all configured

watchdog time-outs.
