Micrel Develops MIC384, 3-Zone Thermal Supervisor IC
Micrel Semiconductor (San Jose, CA) has developed a three-zone thermal supervisor IC for thermal management using embedded thermal diodes such as those found in Intel Corp.'s Pentium III CPU.
The MIC384, part of a family of system and thermal management products, features one local and two remote temperature measurement zones, a programmable interrupt output and an address selection input. Its operating power supply current is 0.35mA, and the quiescent current in shutdown mode is 1.0uA.
“The MIC384 leverages Micrel's unique ability to interface to a remote thermal diode using only a single IC pin," commented Jim Judkins, product marketing manager. “It allowed us to pack more features into a smaller, lower-cost package. Our testing has shown that our one-wire implementation is capable of accuracy and noise performance as good as or better than competing two-wire implementations."
In 1,000-piece quantities, the MIC384BM, packaged in an 8-pin SOIC, is priced at $1.54 each. The MSOP-08 MIC384BMM is $1.66 each in 1,000-piece quantities. SOIC samples are available from stock.
