1.3 Description  
The LM93, hardware monitor, has a two wire digital interface compatible with SMBus 2.0. Using an 8-bit  
ΣΔ ADC, the LM93 measures the temperature of two remote diode connected transistors as well as its  
own die and 16 power supply voltages.  
To set fan speed, the LM93 has two PWM outputs that are each controlled by up to four temperature  
zones. The fan-control algorithm is lookup table based. The LM93 includes a digital filter that can be  
invoked to smooth temperature readings for better control of fan speed. The LM93 has four tachometer  
inputs to measure fan speed. Limit and status registers for all measured values are included.
