Description
1
SCL
Digital Input (Open Drain). SMBus serial clock input. Requires SMBus pull-up.
2
GND
Ground Pin.
3
VCC
Power Supply. Powered by 3.3 V.
4
TACH3
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 3.
ADDR SELECT
If in address select mode, the logic state of this pin defines the SMBus device address.
5
PWM2
Digital Output (Open Drain). ADT7473 default pin function is PWM2. Requires 10 kΩ typical pull-up. Pulse-width
modulated output to control Fan 2 speed. Can be configured as a high or low frequency drive.
SMBALERT
On the ADT7473, this pin can be reconfigured as an SMBALERT interrupt output to signal out-of-limit conditions.
THERM_LATCH
ADT7473-1 default pin function. THERM_LATCH is a thermal event alert signal when an overtemperature
condition occurs.
6
TACH1
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 1.
7
TACH2
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 2.
8
PWM3
Digital I/O (Open Drain). Pulse-width modulated output to control the speed of Fan 3 and Fan 4. Requires 10 kΩ
typical pull-up. Can be configured as a high or low frequency drive.
ADDREN
If pulled low on power-up, the ADT7473-1 enters address select mode, and the state of Pin 4 (ADDR SELECT)
determines the ADT7473-1 slave address.
9
TACH4
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 4.
GPIO
General-Purpose Open Drain Digital I/O.
THERM
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 Pentium 4 processor or to the output of a trip point temperature sensor. Can be
used as an output to signal overtemperature conditions.
SMBALERT
Digital Output (Open Drain). This pin can be reconfigured as an SMBALERT interrupt output to signal out-of-limit
conditions.
10
D2
Cathode Connection to Second Thermal Diode.
11
D2+
Anode Connection to Second Thermal Diode.
12
D1
Cathode Connection to First Thermal Diode.
13
D1+
Anode Connection to First Thermal Diode.
14
VCCP
Analog Input. Monitors processor core voltage (0 V to 3 V).
15
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 XNOR tree in XNOR test mode.
16
SDA
Digital I/O (Open Drain). SMBus bidirectional serial data. Requires 10 kΩ typical pull-up.
