ISO5852S: the meaning of "Low-level clamp current"

Hi Expert,

May I know the meaning of "Low-level clamp current" this spec in datasheet Page 9? Why the test condition is V(CLAMP) = VEE2 + 2.5 V? Thanks.

Regards,

Jared.

    Jared, 

    This is the current rating for when the miller clamp (CLAMP pin) is connected to the gate. 

    the miller clamp is enabled once the gate voltage reaches 2.5V above the VEE2 (negative supply), so that is where it is measured as at this voltage is when the miller clamp would experience the highest peak current. 

    If you need a general description on miller clamp, see here -> https://www.ti.com/lit/eb/slyy169/slyy169.pdf#page=24
