, and Overvoltage Protection
4 _______________________________________________________________________________________
Note 1: All currents into pins are positive and all currents out of pins are negative. All voltages referenced to V
EE
, unless otherwise
specified.
Note 2: All limits are 100% tested at +25?/SPAN>C and +85?/SPAN>C. Limits at -40?/SPAN>C and -10?/SPAN>C are guaranteed by characterization.
Note 3: V
ON
drops below the V
ON_REF,F
threshold are ignored during this time.
Note 4: Delay time from a valid on condition until the load-probe test begins.
Note 5: The short-circuit threshold is V
SC
= 2 x V
CB
.
Note 6: The time when PGOOD condition is met until PGOOD signal is asserted.
