LM96163 Overview
The LM96163 has remote and local temperature sensors with integrated fan control that includes TruTherm BJT transistor beta pensation technology for remote diode sensing. The LM96163 accurately measures: (1) its own temperature and (2) the temperature of a diode-connected transistor, such as a 2N3904, or a thermal diode monly found on puter Processors, Graphics Processor Units (GPU) and other ASIC's. The LM96163 has an offset register to correct for errors caused by different nonideality factors of other thermal diodes.
