5. These specifications are guaranteed only for the test conditions listed.
6. The accuracy of the aSC7512 is guaranteed when using the thermal diode of a processor or any thermal diode with a non-ideality
of 1.008 and internal series resistance of 3.52
. When using a 2N3904 type transistor as a thermal diode the error band will be
typically shifted depending on transistor characteristics.
7. Accuracy (expressed in °C) = Difference between the aSC7512 reported output temperature and the temperature being
measured. Local temperature accuracy does not include the effects of self-heating. The rise in temperature due to self-heating is
the product of the internal power dissipation of the aSC7512 and the thermal resistance. See (Note 3) for the thermal resistance
to be used in the self-heating calculation.
8. Holding the SMBDAT and/or SMBCLK lines Low for a time interval greater than
t
TIMEOUT
will reset the aSC7512’s SMBus state
machine, therefore setting the SMBDAT pin to a high impedance state.
