DESCRIPTION
PWM-OUT
1
16
Output, open-drain. PWM output to control fan speed.
TACH
2
1
Input. Fan tachometer input to measure the fan speed.
Digital output, open-drain, active low. Goes low when temperature reaches the critical shutdown threshold
or remote temperature sensor failed. (See the
Interrupt
section for details.)

Power supply, +3 to +5V
Digital input/output (open-drain). As an output, an active low output indicates the temperature over the
THERM temperature limit. As an input, the pin provides an external fan control. When the pin is pulled
low by external signal, the THERM-IN bit is set, and the fan is set to full-speed.
THERM

FAN-FAULT
8
7
Open-drain output. Goes low when a fan failure is detected.
IN–

8
Negative analog differential input. Connected to cathode of external temperature-sensing diode.
Positive analog differential input. Connected to anode of external temperature-sensing diode
Pentium-IV substrate transistor or general-purpose 2N3904 type transistor.
IN+
10
9
Digital input, PWM mode selection. When tied low (GND), the high PWM frequency range (1kHz to
40kHz) is selected. When tied to V
DD
or floated, the low PWM frequency range (10Hz to 94Hz) is
selected.

Digital output, open-drain, SMBALERT, active low. Requires a pull-up resistor (2.2k
typical).
Bi-directional digital I/O pin, SMBus data, open-drain. Requires a pull-up resistor (2.2k
typical).
