The LM80 provides 7 positive voltage inputs, temperature measurement, fan speed measurement, and hardware monitoring on an I2C™ interface. The LM80 performs WATCHDOG™comparisons of all measured values and an open-drain interrupt output becomes active when any values exceed programmed limits.
Features
Temperature sensing
7 positive voltage inputs
2 programmable fan speed monitoring inputs
10 mV LSB and 2.56V input range accepts outputs from linear temperature sensors such as the LM50
Chassis Intrusion Detector input
WATCHDOG comparison of all monitored values
Separate input to show status in Interrupt Status Register of additional external temperature sensors such as the LM56 or LM75
I2C Serial Bus interface compatibility
Shutdown mode to minimize power consumption
Programmable RST_OUT/OS pin: RST_OUT provides a Reset output; OS provides an Interrupt Output activated by an Overtemperature Shutdown event
Applications
System Thermal and Hardware Monitoring for Servers and PCs
