The NCT7368S device from Nuvoton’s Hardware Monitoring IC family is a PWM comparator that is capable of comparing up to 4 input duty cycles and routing the highest duty cycle to the output.

Update frequency and proportional hysteresis are strap selectable upon system power  on and the NCT7368S also upports thermal hot protection which can be connected to an alert signal from the thermal IC or micro-controller. The NCT7368S is widely used for workstations and server backplane boards.
