Detailed DescriptionThe MAX6678 temperature sensor and fan controlleraccurately measures the temperature of either tworemote pn junctions or one remot

MAX6678SMBus Digital InterfaceFrom a software perspective, the MAX6678 appears as aset of byte-wide registers. This device uses a standardSMBus 2-wire

The DXN input is biased at 0.60V above ground by aninternal diode to set up the analog-to-digital inputs for adifferential measurement. The worst case

MAX6678PWM Output1) The PWMOUT_ signals are normally used in one ofthree ways to control the fan’s speed: PWMOUT_ dri-ves the gate of a MOSFET or the

The duty cycle of the PWM can be controlled in two ways:1) Manual PWM control by setting the duty cycle of thefan directly through the fan target duty
