Electrical Specifications
Temperature Sensor with Serial Presence-Detect EEPROM
The temperature sensor continuously monitors the module’s temperature and can be
read back at any time over the I2C bus shared with the SPD EEPROM.
EVENT# Pin
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 in Figure 3 on page 12. 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# will trigger whenever the temperature is outside the MIN or MAX values set by
the user.
