    The NTC resistance at the set point T2 and release point T1 
    of VR_FAN signal can be calculated as:
    With the NTC resistance value obtained from Equations17 & 
    18, the temperature value T2 and T1 can be found from the 
    NTC datasheet.
    Temperature Compensation 
    ISL6316 supports inductor DCR sensing, MOSFET R
    DS(ON)
    sensing, or resistive sensing techniques. Both inductor DCR 
    and MSOFET R
    DS(ON)
     have the positive temperature 
    coefficient, which is about +0.38%/°C. Because the voltage 
    across inductor or MOSFET is sensed for the output current 
    information, the sensed current has the same positive 
    temperature coefficient as the inductor DCR or MOSFET 
    R
    DS(ON)
    .
    In order to obtain the correct current information, there should 
    be a way to correct the temperature impact on the current 
    sense component. ISL6316 provides two methods: integrated 
    temperature compensation and external temperature 
    compensation. 
    Integrated Temperature Compensation
    When TCOMP voltage is equal or greater than Vcc/15, 
    ISL6316 will utilize the voltage at TM and TCOMP pins to 
    compensate the temperature impact on the sensed current. 
    The block diagram of this function is shown in Figure 17.
