APPLICATIONS INFORMATION
Temperature Thresholds
The threshold voltages at VT1 and VT2 can be set with
the 1.8V reference voltage (VREF) and a resistive divider
as shown in Figure 5.
The following design procedure can be used to size the
resistive divider.
1. Calculate Threshold Voltages:
VT1
= T1• 4
mV
K
•
ηACT
1.004
VT2
= T2 • 4
mV
K
•
ηACT
1.004
where
ηACT denotes the actual ideality factor if an external
sensor is used and T1 and T2 are the desired threshold
temperatures in degrees Kelvin.
2. Choose RTA to obtain the desired VT1 threshold for
a desired current through the resistive divider
(IREF):
RTA =
VT1
IREF
3. Choose RTB to obtain the desired VT2 threshold:
RTB =
VT2 – VT1
