Notes
29.
Output Rise and Fall time respectively measured across a 26
Ω resistive load at 10 to 90 percent, and 90 to 10 percent voltage points.
30.
Output Turn ON Delay time measured from 50 percent rising edge of CS to 90 percent of Output OFF voltage (VPWR) with RL = 26Ω
resistive load.
31.
Output Turn OFF Delay time measured from 50 percent rising edge of CS to 10 percent of Output OFF voltage (VPWR) with RL = 26Ω
resistive load.
32.
Output Short Fault Delay time measured from rising edge of CS to IOUT -= 2.0A point with output ON, VOUT = 5.0V, and SFPD = 0.2
VDD. See Figures 8 and 10.
33.
Output OFF Fault Report Delay measured from 50 percent rising edge of CS to rising edge of output. See Figure 9.
34.
Clock period include 75ns rise plus 75ns fall transition in addition to clock high and low time.
35.
RST Low duration measured with outputs enabled and going to OFF or disabled condition.
36.
Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
37.
Time required for output status data to be available for use at the SO pin.
38.
Time required for output status data to be terminated at the SO pin.
39.
Time required to obtain valid data out from SO following the rise of SCLK. See Figure 5.
