and does not go inactive until the temperature drops

.
Enable thermostat mode through the configuration reg-
ister (Table 4), with one bit to enable the feature and
another bit to set the output polarity (active high or
active low). The
ALERT
thermostat comparison is made
after each conversion, or at the end of any SMBus
transaction. For example, if the limit is changed while
the device is in standby mode, the
ALERT
output
responds correctly according to the last valid A/D
result. Upon entering thermostat mode, the
ALERT
out-
put is reset so that if the temperature is in the hysteresis
band
ALERT
initially goes inactive. The power-on reset
(POR) state disables thermostat mode.
Diode Fault Alarm
A continuity fault detector at DXP detects whether the
remote diode has an open-circuit condition, short-cir-
cuit to GND, or short-circuit DXP-to-DXN condition. At
the beginning of each conversion, the diode fault is
checked, and the status byte is updated. This fault
detector is a simple voltage detector; if DXP rises
