LM88 Datasheet (National Semiconductor) - Factory Programmable Dual Remote-Diode Thermostat

LM88, Factory Programmable Dual Remote-Diode Thermostat

The LM88 is a dual remote-diode temperature sensor with 3 digital comparators.

The LM88 has 3 open-drain outputs (O_SP0, O_SP1 and O_CRIT) that can be used as interrupts or to signal system shutdown.

The digital comparators can be factory programmed to make a greater than or less than comparison.
