TI recommends that users avoid shaping the signals to the gate driver in an attempt to slow down (or delay) the signal at the output. However, a small input filter, RIN-CIN, can be used to filter out the ringing introduced by nonideal layout or long PCB traces.
Such a filter should use an RIN resistor with a value from 0 Ω to 100 Ω and a CIN capacitor with a value from 10 pF to 1000 pF. In the example, the selected value for RIN is 51 Ω and CIN is 33 pF, with a corner frequency of approximately 100 MHz.
When selecting these components, pay attention to the trade-off between good noise immunity and propagation delay.
