General Description
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.
