EVENT output
The STTS751 EVENT output is open drain and requires a pull-up resistor.
The EVENT pin is asserted (low) whenever the temperature exceeds the high limit or is
equal to or below the low limit. Once asserted, the output will remain asserted until the
STTS751 receives an SMBus Alert Response Address (ARA) from the host and
acknowledges with its slave address. The output will be deasserted when the ARA is
acknowledged. If the triggering condition is still true, the output will be reasserted at the next
temperature conversion.
