?1?C Remote Diode Temperature Sensor with PWM Fan Control and 5 GPIO`s
LM64 Product Folder The LM64 is a +/-1°C accurate remote diode digital temperature sensor with integrated fan control.
This evaluation board is designed to ease the evaluation and design-in of National Semiconductor's LM64 remote diode fan controller. The LM64EVAL board connects via USB to a PC and is controlled by SensorEval software, which is included in the kit. SensorEval allows access and control of the LM64's registers. The LM64EVAL board includes headers and jumpers for controlling and possibly remotely connecting the digital I/O pins of the LM64. The LM64EVAL is mainly powered through the USB connection. Fan drive circuitry is provided on the board. Fan drive power is not acquired from the USB connection and requires an external power supply.
Features:
- Accurately senses remote and local diode temperatures
- Integrated PWM fan speed control output
- Programmable 8-step Lookup Table for quieting fans
- ALERT# and T_Crit# open-drain outputs
