Description of the state Z“
The state Z“ has, depending on the previous operating condition different meaning.
1. dynamical
I. e. the inductive load is current carrying and is switched off according to Pos. 5, 6, 9, 10, 11, 12, 13, or
14 of the truth table
a.) All output stage transistors are switched off.
b.) The current flow is continued via the free wheeling diodes.
c.) Free wheeling is detected by a negative voltage-level at OUn.
d.) Switch on of the parallel-transistor of the current carrying diode.
f.) Free wheeling is finshed, if the voltage-level on OUn is positive again.
2. statical
g.) all output-stages switched off.
