... OUT3 Actual limits are shown in graphs in the Typical Performance Characteristics section. Thermal As power in the NCV8612B increases, it might become ) and drives the gate necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material, and the ambient temperature affect the rate of junction temperature rise for the part ...

... The HV_DET signal will reassert high once the HV_DET signal crosses the HV_DET threshold going low. The NCV8612B is also equipped with a Hot Flag pin which indicates when the junction temperature is approaching thermal shutdown. The Hot Flag signal will remain high as long as the junction temperature is below the Hot flag threshold, typically 140° ...
