LM96194
TruTherm Hardware Monitor with PI Fan Control for
Workstation Management
1.0 General Description
The LM96194 hardware monitor has a two wire digital inter-
face compatible with SMBus 2.0. Using a
ΣΔ ADC, the
LM96194 measures the temperature of four remote diode
connected transistors as well as its own die and 9 power sup-
ply voltages. The LM96194 has new TruTherm technology
that supports precision thermal diode measurements of pro-
cessors on sub-micron processes.
To set fan speed, the LM96194 has two PWM outputs that
are each controlled by up to six temperature zones. The fan-
control algorithm can be based on a lookup table, PI (propor-
tional/integral) control loop, or a combination of both. The
LM96194 includes digital filters that can be invoked to smooth
temperature readings for better control of fan speed such that
acoustical noise is minimized. The LM96194 has four
tachometer inputs to measure fan speed. Limit and status
registers for all measured values are included.
The LM96194 includes most of the features of the LM94, dual
CPU motherboard server management ASIC, such as mea-
surement and control support for dynamic Vccp monitoring for
VRD10/11 and PROCHOT but is targeted for single proces-
sor systems.
