Error Detection
The status output signal of the switching stages at normal operation is LOW = OFF; HIGH = ON. In
case of any error the status outputs are set according to the table below. If current overload or thermal
overload occurs, the error condition is stored in an internal register and the output is shutdown. To
reset this register the control input of the affected channel has to be switched off and then on again.
The state of the error detection circuit is directly dependent on the input status.
Open load is detected for both on- and off-modus.
In the on-modus the load current is monitored. If it drops below the specified threshold open load is
detected. In the off mode, the ouput voltage is monitored.
An open load condition is detected when the output voltage of a given channel is below 55 % of the
supply voltage V
condition with a fixed offset of typ. 1.25 V to recognize GND bypasses. To suppress fault diagnosis
during the flyback phase of the compared output, the diagnostic circuit includes a latch function. Reset
of this latch is done at end of the flyback phase, additionally it can be reseted by a low signal on the
enable input and by a high signal of the input signal. See also the block diagramm of open load detec-
tion.
