LM64 Features

* a PWM, open-drain, fan control output, 5 GPIO (General Purpose Input/Output) and 5 GPD (General Purpose Default) pins. The 8-step Lookup Table allows for a non-linear fan speed vs. temperature transfer function often used to quiet acoustic fan noise. Key Specifications n Remote Diode Temperature Ac

LM64 General Description

The LM64 is a remote diode temperature sensor with PWM fan control. The LM64 accurately measures its own temperature and that of a remote diode. The LM64 remote temperature accuracy is factory trimmed for a MMBT3904 diodeconnected transistor with a 16˚C offset for high temperatures. TACTUAL DIODE JU.
