Using a ΣΔ ADC, the LM96194 measures the temperature of four remote diode connected transistors as well as its own die and 9 power supply voltages. The LM96194 has new TruTherm technology that supports precision thermal diode measurements of processors 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 (proportional/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 measurement and control support for dynamic Vccp monitoring for VRD10/11 and ^PROCHOT but is targeted for single processor systems.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
