... MIC280 General Description The MIC280 is a digital thermal supervisor capable of measur- ing its own internal temperature and that of a remote PN junc- tion. The remote junction may be an inexpensive commodity transistor, e.g., 2N3906 embedded thermal diode such as found in Intel Pentium* II/III/IV CPUs, AMD Athlon* CPUs, and Xilinx Virtex* FPGA's ...

... Table 4. FAULT QUEUE A set of fault queues (programmable digital filters) are pro- vided in the MIC280 to prevent false tripping due to thermal or electrical noise. Two bits, CONFIG[5:4], set the depth of the fault queues. The fault queue setting then determines the number of consecutive temperature events (TEMPx > ...

... This includes reset- ting bits the security register, LOCK. The state of the MIC280 following this operation is indistinguishable from a power-on reset. If the reset bit is set while the MIC280 is shut down, the shutdown bit is cleared and normal operation resumes from the reset state. ...

... MIC280 will not shut down under any circumstances. Attempts to set the SHDN bit will be ignored and all chip functions will remain operational set while the MIC280 is in shutdown mode, it will immediately exit shutdown mode and resume normal operation. It will not be possible to subsequently re- enter shutdown mode. Setting L4 disables the RST bit in the confi ...

... TEMP1h. The complete remote temperature result in both TEMP1h and TEMP1l may be obtained by performing a Read_Word operation on TEMP1h. The MIC280 will respond to a Read_Word with a command byte of 01h (TEMP1h) by returning the value in TEMP1h followed by the value in TEMP1l. This guarantees that the data in both registers is from the same temperature-to-digital conversion cycle ...

... This typically suggests the use of a 1800pF NP0 or C0G ceramic capacitor with a 10% tolerance. If the remote diode = 3.6V distance of more than 6"-12" from the MIC280, DD using twisted pair wiring or shielded microphone cable for the connections to the diode can significantly reduce noise pickup ...
