WebFeb 10, 2024 · The two-level turn-off (TLTOff) is a voltage controlled turn-off function. Two-level turn-off supports secure IGBT turn-off in both normal off condition and fault turn off condition. For more details, I would recommend you to read the page 21-23 of the application note. View solution in original post. 0 Likes. WebMar 31, 2024 · I see. For the two-level turn off the gate driver uses the soft turn off current (ITL3 which is typically 500-1200mA) which constrains how fast the gate voltage decreases. The initial ramp down is also pulled down with the soft turn off. Here is an example waveform from another device with the same behavior: Best, Nancy
