DC-DC Converter for IGBT Driver QC962-8A The short-circuit detection time delay is defined between the time in which a desaturation is detected and the time in which the gate voltage fall down to 90% of extent. This diver have a minimum short-circuit detection time delay, and you can adjust the short-circuit detection time delay by connecting the capacitor (Ctrip). But the short-circuit detection time delay must be set less than 3.5μS. Please refer to below table.(the data only for refer). R1 Protective inhibition test Increase the protective inhibition time Reduce the protective inhibition time...
