Description
Digital Input (Open Drain). SMBus serial clock input. Requires SMBus pullup.
Ground Pin.
Power Supply. Powered by 3.3 V.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 3.
If in address select mode, the logic state of this pin defines the SMBus device address.
Digital Output (Open Drain). ADT7473 default pin function is PWM2. Requires 10 k W typical pullup.
Pulse-width modulated output to control Fan 2 speed. Can be configured as a high or low frequency
drive.
On the ADT7473, this pin can be reconfigured as an SMBALERT interrupt output to signal out-of-limit
conditions.
ADT7473 ? 1 default pin function. THERM_LATCH is a thermal event alert signal when an
overtemperature condition occurs.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 1.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 2.
Digital I/O (Open Drain). Pulse-width modulated output to control the speed of Fan 3 and Fan 4.
Requires 10 k W typical pullup. Can be configured as a high or low frequency drive.
If pulled low on powerup, the ADT7473 ? 1 enters address select mode, and the state of Pin 4
(ADDR SELECT) determines the ADT7473 ? 1 slave address.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 4.
General Purpose Open Drain Digital I/O.
Bidirectional THERM pin. Can be used to time and monitor assertions on the THERM input as well as
to assert when an ADT7473 THERM overtemperature limit is exceeded. For example, the pin can be
connected to the PROCHOT output of an Intel R Pentium R 4 processor or to the output of a trip point
temperature sensor. 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 3.0 V).
Digital Output (Open Drain). Pulse-width modulated output to control Fan 1 speed. Requires 10 k W
typical pullup.
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 pullup.
