LM8850 - Factory Programmable Dual Remote-Diode Thermostat

Datasheet Summary

Description

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

The LM88 has 3 opendrain 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.
