A miniature, two-zone thermal supervisor IC, the MIC280, features highly accurate remote temperature measurement capabilitiesÑ±1¡C from 60¡C to 100¡C. Other features include programmable resolution up to 12 bits for the remote zone, six independent channels, I2C/SMBus compatibility, and a programmable thermostatic setting for both local and remote zones. The device, also called the Precision Itty Bitty Thermal Supervisor, is available in 6-pin SOT23 packaging. System reliability is enhanced through such features as locking of critical functions, a serial bus timeout, and reporting of diode faults. Fault queues prevent nuisance tripping. Operating power supply current is 3 mA, while quiesccnt current in shutdown mode is just 5 mA. Pricing of the MIC280 is $1.34 each/ 1,000. MICREL SEMICONDUCTOR, San Jose, CA. (408) 944-0800.
