1 remote and local temp sensor with fan control and 5 GPIO's

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 diode-connected transistor with a 16°C offset for high temperatures.

TACTUAL DIODE JUNCTION = TLM64 +

16°C

The 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.
