Notes
19. Rise and Fall Slew Rates A measured across a 5.0 ?? resistive load at high side output = 0.5 V to V PWR - 3.5 V. These parameters are
guaranteed by process monitoring.
20. Rise and Fall Slow Slew Rates B measured across a 5.0 ?? resistive load at high side output = V PWR - 3.5 V to V PWR - 0.5 V. These
parameters are guaranteed by process monitoring .
21. Turn-ON delay time measured from rising edge of any signal (IN, SCLK, CS) that would turn the output ON to V HS = 0.5 V with ?
R L = 5.0 ? resistive load.
22.
Turn-OFF delay time measured from falling edge of any signal (IN, SCLK, CS) that would turn the output OFF to V HS = V PWR - 0.5 V
with R L = 5.0 ? resistive load.
