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. A Chassis Intrusion input is provided to monitor
and reset an external circuit designed to latch a chassis intrusion event.
The LM80 is especially suited to interface to both linear and digital temperature
sensors. The 10 mV LSB and 2.56 volt input range is ideal for accepting inputs from a linear sensor
such as the LM50. The BTI is used as an input from either digital or
thermostat sensors such as LM75 and LM56.
The LM80's 2.8V to 5.75V supply voltage range, low supply current, and
I2C interface make it ideal for a wide range of applications. These
include hardware monitoring and protection applications in personal computers, electronic test
equipment, and office electronics.
