MC3 failure reaction

What happens if the application running on the MC3 crashes? Does the safety ASIC reacts and brings all of the outputs to a safe state (unpowered)? Thanks!


Yes, the application execution will be stopped which switches off all the IQAN-MC3 power drivers using both the high-side (COUT DOUT high side pins) and low-side drivers (CRET, DRET pins). The safety ASIC will at the same time switch off supply to all the high-side drivers via the internal shared high-side driver.
