DETAILED DESCRIPTION
The output, V OUT , stays valid until the input voltage falls
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
below the minimum operating voltage, V IN MIN , of 0.7V.
Below this minimum operating voltage, the output is
undefined. During power-up or anytime V IN has fallen
below V IN MIN , V OUT will remain undefined until V IN rises
above V IN MIN , at which time the output becomes valid.
V OUT is maintained in its active low state while V IN MIN <
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).
