LM96163 具有 Int 风扇控制和 TruTherm BJT 晶体管 Beta 补偿技术的远程二极管数字温度传感器
The LM96163 has remote and local temperature sensors with integrated fan control that includes TruTherm BJT transistor beta compensation 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 commonly found on Computer Processors, Graphics Processor Units (GPU) and other ASIC's. The LM96163 has an offset register to correct for errors caused by different non-ideality factors of other thermal diodes.
The LM96163 also features an integrated, pulse-width-modulated (PWM), open-drain fan control output. Fan speed depends on a combination of the remote temperature reading, the lookup table and register settings.
