Description
1
PWM_OUT1
Digital Output, Open−Drain. Pulse width modulated output to control fan speed. Requires pullup
resistor (10 kW typical).
2
TACH1/AIN1
Digital/Analog Input. Fan tachometer input to measure FAN1 fan speed. Can be reprogrammed as an
analog input to measure speed of a 2−wire fan via a sense resistor (2 W typical).
3
PWM_OUT2
Digital Output, Open−Drain. Pulse width modulated output to control FAN2 fan speed. Requires
pullup resistor (10 kW typical).
4
TACH2/AIN2
Digital/Analog Input. Fan tachometer input to measure FAN2 fan speed. Can be reprogrammed as an
analog input to measure speed of a 2−wire fan via a sense resistor (2 W typical).
5
GND
System Ground.
6
VCC
Power. Can be powered by 3.3 V standby power if monitoring in low power states is required.
7
THERM
Digital I/O, Open−Drain. An active low thermal overload output that indicates a violation of a
temperature set point (overtemperature). Also acts as an input to provide external fan control. When
this pin is pulled low by an external signal, a status bit is set, and the fan speed is set to full−on.
Requires pullup resistor (10 kW).
8
FAN_FAULT
Digital Output, Open−Drain. Can be used to signal a fan fault. Drives second fan to full speed if one
fan fails. Requires pullup resistor (typically 10 kW).
9
D1–
Analog Input. Connected to cathode of first remote temperature−sensing diode. The
temperature−sensing element is either a Pentium III substrate transistor or a general−purpose
2N3904.
10
D1+
Analog Input. Connected to anode of first remote temperature−sensing diode.
11
D2–
Analog Input. Connected to cathode of second remote temperature−sensing diode.
12
D2+
Analog Input. Connected to anode of second remote temperature−sensing diode.
13
ADD
Three−State Logic Input. Sets two lower bits of device SMBus address.
14
INT(SMBALERT)
Digital Output, Open−Drain. Can be programmed as an interrupt (SMBus ALERT) output for
temperature/fan speed interrupts. Requires pullup resistor (10 kW typical).
15
SDA
Digital I/O, Serial Bus Bidirectional Data. Open−drain output. Requires pullup resistor (2.2 kW typical).
16
SCL
Digital Input, Serial Bus Clock. Requires pullup resistor (2.2 kW typical).
ELECTRICAL CHARACTERISTICS TA = TMIN to TMAX, VCC = VMIN to VMAX, unless otherwise noted. (Note 1)
