Temperature Sensor with Serial Presence-Detect EEPROM Operating Conditions
Sensor Serial Interface Timing
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 shown in Figure 3 on page 14. Event thresholds are programmed in
the 0x01 register 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 boundary register, respectively. When the alarm window is enabled, EVENT# trig-
gers whenever the temperature is outside the MIN or MAX values set by the user.
The interrupt mode enables software to reset EVENT# after a critical temperature
threshold has been detected. Threshold points are set in the configuration register by the
user. This mode triggers at the critical temperature limit and at the MIN and MAX points
of the temperature alarm window.
