Three phase coolStep(TM) stepper motor driver IC with step/direction and stallGuard2(TM)
In Page 27 of TMC389 datasheet, there is a formula Tslope = Qmiller/Igate. But I go through all datasheet, I cannot found Igate coming from. Could anybody advise?

You find the gate driver currents in the NMOS / PMOS driver sections in DC characteristics.
