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.

Figure 6 below shows how the EVENT output functions.
