PRODUCT DESCRIPTION
The ADM1030 is an ACPI-compliant two-channel digital ther-
mometer and under/over temperature alarm, for use in computers
and thermal management systems. Optimized for the Pentium
III, the higher 1
°C accuracy offered allows systems designers to
safely reduce temperature guardbanding and increase system
performance. A Pulsewidth Modulated (PWM) Fan Control out-
put controls the speed of a cooling fan by varying output duty
cycle. Duty cycle values between 33%–100% allow smooth
control of the fan. The speed of the fan can be monitored via a
TACH input for a fan with a tach output. The TACH input can
be programmed as an analog input, allowing the speed of a 2-wire
fan to be determined via a sense resistor. The device will also
detect a stalled fan. A dedicated Fan Speed Control Loop pro-
vides control even without the intervention of CPU software. It
also ensures that if the CPU or system locks up, the fan can still
be controlled based on temperature measurements, and the fan
speed adjusted to correct any changes in system temperature.
Fan Speed may also be controlled using existing ACPI software.
One input (two pins) is dedicated to a remote temperature-
sensing diode with an accuracy of
±1°C, and a local temperature
sensor allows ambient temperature to be monitored. The device
has a programmable
INT output to indicate error conditions.
There is a dedicated
FAN_FAULT output to signal fan failure.
The
THERM pin is a fail-safe output for over-temperature
conditions that can be used to throttle a CPU clock.
*Patents pending.
