PIN NAME
VR_HOT
TM
GND
DESCRIPTION
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 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.
Bias and reference ground for the IC. The bottom metal base of ISL6336D is the GND.
