dBCool® Remote Thermal Controller and Voltage Monitor

ON Semiconductor 

ADT7468

Pin

No. Mnemonic Description

16 D2+

Anode Connection to Second Thermal Diode.

17 D1–

Cathode Connection to First Thermal Diode.

18 D1+

Anode Connection to First Thermal Diode.

19 VID4

Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).

20 +5VIN

Analog Input. Monitors +5 V power supply.

THERM

Alternatively, this pin can be reconfigured as a bidirectional THERM pin. Can be used to time and monitor assertions

on the THERM input. For example, it can be connected to the PROCHOT output of an Intel Pentium 4 processor or to

the output of a trip point temperature sensor. This pin can also be used as an output to signal overtemperature

conditions.

21 +12VIN

Analog Input. Monitors +12 V power supply.

VID5

Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).

Supports VRM10 solutions.

22 +2.5VIN

Analog Input. Monitors +2.5 V supply, typically a chipset voltage.

23

VCCP

Analog Input. Monitors processor core voltage (0 V to 3 V).

24 PWM1

Digital Output (Open Drain). Pulse width modulated output to control Fan 1 speed. Requires 10 kΩ typical pull-up.

XTO

Also functions as the output from the XOR tree in XOR test mode.
