This device, also called SQuare wave timer,  allow to generate square waves with variable duty-cycle. When the input is asserted, the time elapsing proceeds. When the elapsed time reaches the pre-programmed threshold, applied to the input PT#1, the Q output become TRUE. Time elapsing continue until the second pre-programmed threshold, applied to the input PT#2 is reached. When this condition become true, the Q output is putted to OFF state and the elapsed time is cleared so a new cycle could begin.

 

De-asserting the IN input will freeze the timer in the last condition. Applying a ON state again on the IN input will start the timer at the same point where it was left.

The ET output pin reports the current elapsed time.

Description



IN

The square wave generation proceeds when this input is asserted

 

 

PT#1

The Q output become TRUE when the elapsed time reaches the value applied to this input. User should use an IDENT object to enter a time constant

 

 

PT#2

The Q output become FALSE when the elapsed time reaches the value applied to this input. User should use an IDENT object to enter a time constant

 

 

Q

This output is function of the pre-programmed time PT#1 and PT#2

 

 

ET

This output reports the current elapsed time
