Product Summary
The LM80CIMT-3 is a Serial Interface ACPI-Compatible Microprocessor System Hardware Monitor. It provides 7 positive voltage inputs, temperature measurement, fan speed measurement, and hardware monitoring on an I2C interface. The LM80CIMT-3 performs WATCHDOG comparisons of all measured values and an open-drain interrupt output becomes active when any values exceed programmed limits. The applications of the LM80CIMT-3 are System Thermal and Hardware Monitoring for Servers and PCs, Office Electronics, Electronic Test Equipment and Instrumentation.
Parametrics
LM80CIMT-3 absolute maximum ratings: (1)Positive Supply Voltage (V+):6.5V; (2)Voltage on Any Input or Output Pin:-0.3V to (V++0.3V); (3)Ground Difference (GND - GNDA):±300 mV; (4)Input Current at any Pin:±5mA; (5)Package Input Current:±20 mA; (6)Maximum Junction Temperature(TJ max):150℃; (7)ESD Susceptibility:Human Body Model:2000V, Machine Model:125V; (8)Storage Temperature:-65℃ to +150℃.
Features
LM80CIMT-3 features: (1)Temperature sensing; (2)7 positive voltage inputs; (3)2 programmable fan speed monitoring inputs; (4)10 mV LSB and 2.56V input range accepts outputs from linear temperature sensors such as the LM50; (5)Chassis Intrusion Detector input; (6)WATCHDOG comparison of all monitored values; (7)Separate input to show status in Interrupt Status Register of additional external temperature sensors such as the LM56 or LM75; (8)I2C Serial Bus interface compatibility; (9)Shutdown mode to minimize power consumption; (10)Programmable RST_OUT/OS pin: RST_OUT provides a Reset output; OS provides an Interrupt Output activated by an Overtemperature Shutdown event.
