The temperature sensor continuously monitors the module’s temperature and can be
read back at any time over the I
The temperature sensor also adds the EVENT# pin (open drain). Not used by the SPD
EEPROM, EVENT# is a temperature sensor output used to flag critical events that can
be set up in the sensor’s configuration register.
EVENT# has three defined modes of operation: interrupt mode, compare mode, and
critical temperature mode. The open-drain output of EVENT# under the three separate
operating modes is illustrated below. Event thresholds are programmed in the 0x01 reg-
ister using a hysteresis. The alarm window provides a comparison window, with upper
and lower limits set in the alarm upper boundary register and the alarm lower boun-
dary register, respectively. When the alarm window is enabled, EVENT# will trigger
whenever the temperature is outside the MIN or MAX values set by the user.
