DESCRIPTION
The LM88 is a dual remote-diode temperature sensor with 3 digital parators. 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 parators can be factory programmed to make a greater than or less than parison. When programmed for a greater than parison outputs:
O_SP0 and O_SP1 activate when the temperatures measured by D0 or D1 exceed the associated setpoints of T_SP0 or...
