Preliminary
Publication Release Date: April 1999
- 13 - Revision 0.55
6.3.3 Monitor temperature from thermistor:
The W83783S can connect three thermistors to measure three different envirment temperature. The
specification of thermistor should be considered to (1)
β
value is 3435K, (2) resistor value is 10K
ohms at 25
°
C. In the Figure 11, the themistor is connected by a serial resistor with 10K Ohms, then
connect to VREF (Pin 37).
6.3.4 Monitor temperature from Pentium II
TM
thermal diode or bipolar transistor 2N3904
The W83783S can alternate the thermistor to Pentium II
TM
(Deschutes) thermal diode interface or
transistor 2N3904 and the circuit connection is shown as Figure 12. The pin of Pentium II
TM
D- is
connected to power supply ground (GND) and the pin D+ is connected to pin PIIx in the W83783S.
The resistor R=30K ohms should be connected to VREF to supply the diode bias current and the
bypass capacitor C=3300pF should be added to filter the high frequency noise. The transistor 2N3904
should be connected to a form with a diode, that is, the Base (B) and Collector (C) in the 2N3904
should be tied togeter to act as a thermal diode.
