I have connected via SPI LPC54102 to the MC33908. The MC33908 has two pins IO_4 and IO_5 that can be used as output driver gate.

Output gate driver: Can drive a logic level low-side NMOS transistor. Controlled by the SPI.

I am not clear how to connect to a Dual NMOS (BUK7K5R1-30E).

Is mandatory to connect a 5.1K resistor in serie?

I have made an example (attached) but I guess that is not work.

Best Regards.
