DETAILED DESCRIPTION
In normal steady-state operation when VIN >VDET –,
the output will be at a logic-high (see Figure 3-1). In the
case of the TC54VN, this is an open-drain condition. If
the input falls below VDET –, the output will pull down
(Logic 0) to VSS. Generally, VOUT can pull down to
within 0.5V of VSS at rated output current and input
voltage.
(See
The output (VOUT) will stay valid until the input voltage
falls below the minimum operating voltage (VINMIN) of
0.7V. Below this minimum operating voltage, the output
is undefined. During power-up (or anytime VIN has
fallen below VINMIN), VOUT will remain undefined until
VIN rises above VINMIN. When this occurs, the output
will become valid. VOUT will be in its Active-low state,
while VINMIN <VIN <VDET+ (therefore, VDET+ = VDET
+ VHYST). If the input rises above VDET+, the output will
assume its Inactive state (high for TC54VC, open-drain
for TC54VN).
