Micrel Semiconductor has developed a three-zone thermal supervisor IC for thermal management using embedded thermal diodes such as those found in Intel Corporation's Pentium III CPU. The MIC384 is part of a growing family of system and thermal management products from Micrel. Available in 8-pin MSOP and SOIC packaging, the MIC384 features one local and two remote temperature measurement zones, I2
C/SMBus compatibility, a programmable interrupt output, and an address selection input.
The MIC384's operating power supply current is a portable-friendly 0.35mA, and the quiescent current in shutdown mode is only 1.0 uA. Two package options are available. The MIC384BM is packaged in an 8-pin SOIC, whereas the MIC384BMM comes in a smaller 8-pin MSOP.
