LM96000  
Hardware Monitor with Integrated Fan Control  
Noise filtering of temperature reading for fan control  
General Description  
1.0°C digital temperature sensor resolution  
3 PWM fan speed control outputs  
The LM96000, hardware monitor, has a two wire digital inter-  
face compatible with SMBus 2.0. Using an 8-bit ΣΔ ADC, the  
LM96000 measures:  
Provides high and low PWM frequency ranges  
4 fan tachometer inputs  
– the temperature of two remote diode connected transis-  
tors as well as its own die  
Monitors 5 VID control lines  
24-pin TSSOP package  
– the VCCP, 2.5V, 3.3VSBY, 5.0V, and 12V supplies (in-  
ternal scaling resistors).  
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 temper-  
ature 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.
