Description
Digital Input (Open Drain). SMBus serial clock input. Requires SMBus pull-up.
Ground Pin for the ADT7467.
Power Supply. Can be powered by 3.3 V standby if monitoring in low power states is required. V CC is also
monitored through this pin. The ADT7467 can also be powered from a 5 V supply. Setting Bit 7 of
Configuration Register 1 (0x40) rescales the V CC input attenuators to correctly measure a 5 V supply.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 3. Can be reconfigured as an
analog input (AIN3) to measure the speed of 2-wire fans (low frequency mode only).
Digital Output (Open Drain). Requires 10 k W typical pull-up. Pulse width modulated output to control the
speed of Fan 2. Can be configured as a high or low frequency drive.
Digital Output (Open Drain). This pin can be reconfigured as an SMBALERT interrupt output to signal
out-of-limit conditions.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 1. Can be reconfigured as an
analog input (AIN1) to measure the speed of 2-wire fans (low frequency mode only).
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 2. Can be reconfigured as an
analog input (AIN2) to measure the speed of 2-wire fans (low frequency mode only).
Digital I/O (Open Drain). Pulse width modulated output to control the speed of Fan 3 and Fan 4. Requires
10 k W typical pull-up. Can be configured as a high or low frequency drive.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 4. Can be reconfigured as an
analog input (AIN4) to measure the speed of 2-wire fans (low frequency mode only).
General-Purpose Open-Drain Digital I/O.
Alternatively, the pin can be reconfigured as a bidirectional THERM pin, which can be used to time and
monitor assertions on the THERM input. For example, the pin 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 be used
as an output to signal overtemperature conditions.
Digital Output (Open Drain). This pin can be reconfigured as an SMBALERT interrupt output to signal
out-of-limit conditions.
Cathode Connection to Second Thermal Diode.
Anode Connection to Second Thermal Diode.
Cathode Connection to First Thermal Diode.
Anode Connection to First Thermal Diode.
Analog Input. Monitors processor core voltage (0 V to 3 V).
Digital Output (Open Drain). Pulse width modulated output to control the speed of Fan 1. Requires 10 k W
typical pull-up.
Also functions as the output from the XNOR tree in XNOR test mode.
Digital I/O (Open Drain). SMBus bidirectional serial data. Requires 10 k W typical pull-up.
