During IGBT overcurrent condition, a mute logic initiates a soft-turn-off procedure which disables OUTH and pulls OUTL to low over a time span of 2 μs. When desaturation is active, a fault signal is sent across the isolation barrier pulling the FLT output at the input side low and blocking the isolator input. Mute logic is activated through the soft-turn-off period. The FLT output condition is latched and can be reset only after RDY goes high, through a low-active pulse at the RST input. RST has an internal filter to reject noise and glitches. By asserting RST for at least the specified minimum duration (800ns), device input logic can be enabled or disabled.
