Micrel Semiconductor Inc. (San Jose, CA) announced its new miniature, two-zone, thermal supervisor IC for thermal management using embedded thermal diodes. The MIC280 is available in six-pin SOT23 packaging and features accurate remote temperature measurement, six independent thresholds, I2C/SMBus compatibility, a programmable interrupt output, and numerous features to enhance ease of use and system reliability.
“The main goals in developing the MIC280 were to offer a thermal supervisor with superior real-world accuracy, high reliability, increased programmer friendliness, a smaller footprint and lower cost,” said Jim Judkins, product marketing manager. “The MIC280 fits into about one-fourth the space of legacy thermal supervisor ICs and offers far more features and performance. In many applications such as portable computing and telecom/datacom racks, the thermal envelope is very tight. This has fueled a drive toward more accurate thermal supervisors and led vendors to increase resolution and accuracy specifications.”
The MIC280’s operating power supply current is 3mA and the quiescent current in shutdown mode is only 5µA. Eight different factory-programmed slave address options are available.
In thousand-piece quantities, the MIC280 in six-pin SOT23 packaging is priced at $1.34 each. Samples are from stock and an evaluation board is available.
