Hello! I see the two-wire application using the max6643. However, I didn't find any information about its application in the 4-wire fan which uses the PWM input to adjust the speed. Can Max6643 support a 4-wire fan?

Are you referring to a four-wire fan with Vsupply, GND, TACHO, and PWM? If so, the MAX6643 can support it with VDD, PWM_OUT, two tachometers, and GND.
