CONDITIONS
V OLT = 1.05V, T A = +25 N C
V OLT = 1.05V, T A = +105 N C
A switched open load is blanked for t OL
I OUT < I OL
If V LIM is derived from REF then maximum
voltage at LIM is 3V (Note 2)
V LIM = 2.675V
V LIM = 2.675V, T A = +25 N C
V LIM = 2.675V, T A = +105 N C
Rising V AOUT at which the SC output
asserts low, hysteresis of 40mV,
