PWMx
The following figures show examples of circuitry on the board for the PWM outputs, tachometer inputs,
and remote diodes. Figure B.1, "Fan Drive Circuitry (Apply to PWM Driving Two Fans)" shows how the
part can be used to control four fans by connecting two fans to one PWM output.
Note: These examples represent the minimum required components. Some designs may require
