    Sticky: For the MOSFET version, the input suppression time is 40 ns, how to get longer fi

    Two solutions:
    1) use the IGBT version;
    2) place an RC-filter on the input.

    True, and this was never intended, since the driver does not know which voltage levels a customer uses. Btw, if a power supply fails it will most likely affect both positive and negative supply...

    Sticky: How can the deadtime be set to prevent shoot through for 6ED003L06-F2?

    For the optimum operation, it is necessary to check the transition time of the driven IGBT: the turn-on delay td(on), the rise time tr, the turn-off delay time td(off) and the fall time tf. Also the...

    Sticky: Is the bootstrap diode able to work with a bootstrap capacitance of 10μF?

    Yes, 10 μF CBS is fine. We recommend not designing more than 100 μF for a bootstrap capacitor.

    Sticky: 1ED-family: How do I design the protection diode D_prot at pin DESAT?

    The pin DESAT is not allowed to be forced (even by the junction capacitance of the DESAT diode) below GND2 in any case by more than -0.3V. The only way to achieve this is to use a small signal...

    Sticky: 1ED-family: How can the DESAT function been adjusted for a MOSFET?

    Adjustment can be done by value of the DESAT resistor. The constant current source inside 1ED forces a voltage drop over the DESAT resistor, the DESAT diode and the power device itself, so that the...

    Sticky: What will be the chip output behavior after UVLO recovery?

    For coreless transformer technology based driver IC (1ED-F2/FT/B2/B2 and 1ED-Compact), the output is level (input signal) related, which means after UVLO recovery (e.g. VCC come back to 15V), the...

    Sticky: Is a driver capable of driving a MOSFET/ IGBT?

    In the application, the calculated max. output current from the driver IC should be smaller than the max. spec value according to datasheet (e.g. 2.4A for 1ED-F2).

    Sticky: How to adjust the Desaturation protection level?

    The internal detection level is 9 V, but the triggering level can be set to a lower voltage by increasing the series resistor since we have an integrated current source on chip for DESAT function.

    Sticky: What is the difference between soft turn-off and Two-Level Turn-Off (TLTO)?

    Soft turn-off is done by RC discharging circuit to reduce IGBT gate voltage smoothly. It is mainly used to control the IGBT turn-off speed during short circuit (DESAT) condition, so as to not...

    Sticky: Why does Two-Level Turn-Off function result in a delay time during turn-on?

    When the Two-Level Turn-Off signal finishes, there is a delay time to cut off the output, so the same delay time must be shifted to keep the same on-time.
