ADT7468
Recommended Implementation 2
Configuring the ADT7468 as in Figure 55 provides the system
designer with the following features:
7.
8.
5 V measurement input.
VRM temperature using local temperature sensor.
1.
Six VID inputs (VID0 to VID5) for VRM10 support.
9.
CPU temperature measured using the Remote 1
temperature channel.
2.
3.
4.
5.
6.
Three PWM outputs for fan control of up to three fans.
(All three fans can be individually controlled.)
Three TACH fan speed measurement inputs.
V CC measured internally through Pin 4.
CPU core voltage measurement (V CORE ).
2.5 V measurement input used to monitor CPU current
(connected to V COMP output of ADP316x VRM controller).
This is used to determine CPU power consumption.

10. Ambient temperature measured through the Remote 2
temperature channel.
11. If not using VID5, this pin can be reconfigured as the 12 V
monitoring input.
12. Bidirectional THERM pin allows the monitoring of
PROCHOT output from an Intel P4 processor, for
example, or can be used as an overtemperature THERM
output.
