Description

PWM_OUT
Digital Output (Open-Drain). Pulsewidth modulated output to control fan speed. Requires pull-
up resistor (10 k
typical).
Digital/Analog Input. Fan tachometer input to measure fan speed. May be reprogrammed as an
analog input to measure speed of a 2-wire fan via a sense resistor (2
typical)
Not Connected.
System Ground.
Power. Can be powered by 3.3 V Standby power if monitoring in low power states is required.
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 pull-up resistor (10 k
).
Digital Output (Open-Drain). Can be used to signal a fan failure. Requires pull-up resistor
(typically 10 k
).
Analog Input. Connected to cathode of an external temperature-sensing diode. The temperature-
sensing element is either a Pentium III substrate transistor or a general-purpose 2N3904.
Analog Input. Connected to anode of the external temperature-sensing diode.
Three-state Logic Input. Sets two lower bits of device SMBus address.
Digital Output (Open-Drain). Can be programmed as an interrupt output for temperature/fan
speed interrupts. Requires pull-up resistor (10 k
typical).
Digital I/O. Serial Bus Bidirectional Data. Open-drain output. Requires pull-up resistor
(2.2 k
typical).
Digital Input. Serial Bus Clock. Requires pull-up resistor (2.2 k
typ).
