    Hi,

    We do not have the psi-JT values readily available for this device. Kindly contact local Infineon sales / applications team and they can help trigger an internal request for the same.

    This is not a typo. The data is correct. In the IRS218(4,44), the input pins are no longer internally clamped with 5.2 V zener diodes, therefore the maximum absolute rating for VIN is increased to...

    There are no functional changes between the IRS218(4,44) and the IR218(4,44), however the IRS218(4,44) design has eliminated the input zener clamp diode.

    You try with a bulk capacitor of around 10 uF at the Vcc pin. This should make sure the 1A current limit of LM7815 is not tripped when the driver is switching the MOSFETs.

    Make sure the 10 uF...

    As VBS is going down to 0 V the HO output is switching off. The recharging of the bootstrap capacitor is load dependent and 98% duty cycle is not helping.

    You can test with an isolated 12 V power...

    What is the deadtime between HIN and LIN? Try with a delay between the two and with 50% duty cycle, LIN first and then HIN.
    Try removing the RC across the MOSFETs and the RC at the load L.

    Hi,

    You can provide an initial value to the bootstrap capacitors C17, C23 and check if the error is resolved.

    Thanks.
