VR_HOT

VR_HOT is used as an indication of high VR temperature. It is an open-drain logic output. It will be pulled low if

the measured VR temperature is less than a certain level, and open when the measured VR temperature

reaches a certain level. An external pull-up resistor is needed.

TM

TM is an input pin for the VR temperature measurement. Connect this pin through an NTC thermistor to GND and

a resistor to VCC of the controller. The voltage at this pin is reverse proportional to the VR temperature. The

ISL6336D monitors the VR temperature based on the voltage at the TM pin and outputs VR_HOT and VR_FAN

signals.

GND

Bias and reference ground for the IC. The bottom metal base of ISL6336D is the GND.
