LM96000  
Hardware Monitor with Integrated Fan Control  
n Noise filtering of temperature reading for fan control  
n 1.0˚C digital temperature sensor resolution  
General Description  
The LM96000, hardware monitor, has a two wire digital  
interface compatible with SMBus 2.0. Using an 8-bit Σ∆  
ADC, the LM96000 measures:  
n 3 PWM fan speed control outputs  
n Provides high and low PWM frequency ranges  
n 4 fan tachometer inputs  
n Monitors 5 VID control lines  
n 24-pin TSSOP package  
– the temperature of two remote diode connected transis-  
tors as well as its own die  
– the VCCP, 2.5V, 3.3VSBY, 5.0V, and 12V supplies (in-  
ternal scaling resistors).  
n XOR-tree test mode  
To set fan speed, the LM96000 has three PWM outputs that  
are each controlled by one of three temperature zones. High  
and low PWM frequency ranges are supported. The  
LM96000 includes a digital filter that can be invoked to  
smooth temperature readings for better control of fan speed.  
The LM96000 has four tachometer inputs to measure fan  
speed. Limit and status registers for all measured values are  
included.
