Can you explain how the falling edge high dV/dt transitions of the GHx MOSFET causes a positive pulse on the output from the DRV8303?
We did increase the gate resistors to 20 ohms, from 10; but it had no effect. Our concern with going higher will be heat lost in the TI MOSFET. At 45KHz PWM, what is the maximum resistance the TI MOSET can safely handle?
What is a recommended pull down for the GLx outputs of the DRV8303?
