Digital Input (Open Drain). SMBus serial clock input. Requires SMBus pull-up.
Ground Pin for the ADT7460.
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 ADT7460 can also be powered from a 5 V supply. Setting Bit 7 of
Configuration Register 1 (Reg. 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.
Digital Output (Open Drain). Requires 10 k
typical pull-up. Pulsewidth modulated output to control FAN 2 speed.
Digital Output (Open Drain). This pin may 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.
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.
Digital I/O (Open Drain). Pulsewidth modulated output to control FAN 3/4 speed. Requires 10 k
typical pull-up.
If pulled low on power-up, this places the ADT7460 into Address Select mode, and the state of Pin 9 will
determine the ADT7460’s slave address.
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.
If in Address Select mode, this pin determines the SMBus device address.

Alternatively, the pin may be reconfigured as a bidirectional
THERM
pin. Can be used to time and monitor
assertions on the
THERM
input. For example, can be connected to the
PROCHOT
output of Intel’s Pentium 4
processor or to the output of a trip point temperature sensor. Can be used as an output to signal overtemperature
conditions.

Analog Input. Monitors +2.5 V supply, typically a chipset voltage.
Digital Output (Open Drain). This pin may be reconfigured as an
SMBALERT
interrupt output to signal
out-of-limit conditions.
Digital Output (Open Drain). Pulsewidth modulated output to control FAN 1 speed. Requires 10 k
typical pull-up.
Digital I/O (Open Drain). SMBus bidirectional serial data. Requires SMBus pull up.
