  • 1°C comparator hysteresis
  • 2 setpoints, T_SP0 and T_SP1, factory programmable in 4°C intervals
  • 1 setpoint, T_CRIT, factory programmable in 1°C intervals
  • Active Low open-drain digital outputs
  • 8-pin mini-SO plastic package

LM88CIMM-A 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. When programmed for a greater than comparison outputs:

    O_SP0# and O_SP1# activate when the temperatures measured by D0 or D1 exceed the associated setpoints of T_SP0 or T_SP1.

    O_CRIT# activates when the temperature measured by either D0 or D1 exceeds setpoint T_CRIT.

    T_CRIT can be set at 1°C intervals from -40°C to +125°C. T_SP0 and T_SP1 can be set at 4°C intervals in the range of T_CRIT +127°C/-128°C. Hysteresis for all comparators is set to 1°C. O_CRIT#, in conjunction with T_CRIT, could be used to prevent catastrophic damage to key subsystems such as notebook Card Bus cards while O_SP0# and O_SP1#, in conjunction with T_SP0 and T_SP1, can warn of an impending failure.

    The LM88 is available in an 8-lead mini-small-outline package.
