2.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
3.0 DETAILED DESCRIPTION
In normal steady-state operation and for either
channel, when V
IN
>V
DET
-, the output is high, see
Figure 3-1. (In the case of the TC52N, this is an open-
drain condition.) If and when the input falls below
V
DET
-, the output pulls down (Logic 0) to V
SS
.
Generally, V
OUT
can pull down to within 0.5V of V
SS
at
rated output current and input voltages. (Also see
Section 1.0, Electrical Characteristics).
The output, V
OUT
, stays valid until the input voltage falls
below the minimum operating voltage, V
INMIN
, of 0.7V.
Below this minimum operating voltage, the output is
undefined. During power-up or anytime V
IN
has fallen
below V
INMIN
, V
OUT
will remain undefined until V
IN
rises
above V
INMIN
, at which time the output becomes valid.
V
OUT
is maintained in its active low state while
V
INMIN
<V
IN
<V
DET
+. (V
DET
+=V
DET
-+V
HYST
). If and
when the input rises above V
DET
+, the output will
assume its inactive state (open-drain for TC52N).
