9 / 20 page Preliminary Datasheet TLE 6217 V5 Page 9 of 20 30. 07. 2002 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 VDS(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 tD of typ. 1.2ms (min 500 µs) 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.
