When enabled, the dynamic averaging will affect the average supply current based on the chosen
conversion rate as shown in
The THERM output is asserted independently of the ALERT output and cannot be masked. Whenever
any of the measured temperatures exceed the user programmed THERM Limit values for the
programmed number of consecutive measurements, the THERM output is asserted. Once it has been
asserted, it will remain asserted until all measured temperatures drop below the THERM Limit minus
the THERM Hysteresis (also programmable).
When the THERM pin is asserted, the Therm status bits will likewise be set. Reading these bits will
not clear them until the THERM pin is deasserted. Once the THERM pin is deasserted, the THERM
status bits will be automatically cleared.
