Function Description (CMOS output)
1
When input voltage (V
IN
) rises above detect voltage (V
DF
), output voltage (V
OUT
) will be equal to V
IN
.
(A condition of high impedance exists with Nch open drain output configurations.)
2
When input voltage (V
IN
) falls below detect voltage (V
DF
), output voltage (V
OUT
) will be equal to the ground voltage
(V
SS
) level.
3
When input voltage (V
IN
)falls to a level below that of the minimum operating voltage (V
MIN
), output will become unstable.
In this condition, V
IN
will equal to the pulled-up output (should output be pulled-up).
When input voltage (V
IN
) rises above the ground voltage (V
SS
) level, output will be unstable at levels below the minimum
operating voltage (V
MIN
). Between the V
MIN
and detect release voltage (V
DR
) levels, the ground voltage (V
SS
)level will
4
be maintained.
5
When input voltage (V
IN
) rises above detect release voltage (V
DR
), output voltage (V
OUT
) will be equal to V
IN
.
(A condition of high impedance exists with Nch open drain output configurations).
6
The difference between V
DR
and V
DF
represents the hysteresis range.
