Open load is detected for all four channels in on and off mode.
In the on mode the load current is monitored. If it drops below the specified threshold value IQU then an
open load condition is detected.
In the off mode, the output voltage is monitored. An open load condition is detected when the output
voltage of a given channel is below the threshold V
DS(OL)
, which is typ. 33 % of the supply voltage VS. To
prevent an open load diagnosis in case of transient Voltages on the outputs the open load detection in
off mode uses a filter of typ. 30μs.
Status output at pulse width operation
If the input is operated with a pulsed signal, the status does not follow each single pulse of the input sig-
nal. An internal delay t
D
of typ. 1.2ms (min 500
μ
s) enables a continuous status output signal. See the
timing diagrams on the following pages for further information.
This internal status delay simplifies diagnostic software for pwm applications.
Diagnostic Table
In general the status follows the input signal in normal operating conditions.
If any error is detected the status is inverted.
