Notes

20.

Turn-ON delay time measured from rising edge of any signal (IN, SCLK, CS) that would turn the output ON to VOUT = 0.5 V with RL =5.0 Ω

resistive load.

21.

Turn-OFF delay time measured from falling edge of any signal (IN, SCLK, CS) that would turn the output OFF to VOUT = VPWR-0.5 V with

RL =5.0 Ω resistive load.

22.

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

23.

Watchdog timeout delay measured from the rising edge of WAKE to 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 tWDTO is consistent for all configured watchdog timeouts.

DYNAMIC ELECTRICAL CHARACTERISTICS (continued)

Characteristics noted under conditions 4.5 V

≤ VDD ≤ 5.5 V, 6.0 V ≤ VPWR ≤ 27 V, -40°C ≤ TJ ≤ 150°C unless otherwise noted. Typical

values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions unless otherwise noted.
